Anti Gravity Milk Glass Optical IllusionSammy Salter submitted this cool photo. It represents a glass of milk that somehow managed to beat all those world known scientists trying to break the forces of gravity! Sammy even provided a video clip that proves the authenticity, and shows that no Photshop editing occurred! The solution to this optical illusion in fact is quite simple. Can you solve it? Try it! Be sure to open this article to see all three photos! If you have a spare minute, be sure to check dozen of more interesting video optical illusions inside the “Videos Category“. Enjoy!

    is it frozen?

  2. blackle says:

    i bet its fake plastic milk

  3. Pudding says:

    it vanallia Pudding.

  4. Mabye says:

    Paint? or Pudding?

  5. Rootman says:

    Gelatin added?

  6. db says:

    It isn’t milk, my guess is it’s cream cheese or something like that. I buy glass jars of white spreadable cheese that look pretty much just like that.

  7. Xiam says:

    No, I don’t think it’s frozen. The video shows that the surface quivels when he moves the glas.
    I don’t think it is milk, I don’t even think it is a liquid. It seems to be a semi-solid substance, some kind of gelantine perhaps.

  8. Eggy says:

    xDD Condensed milk!

    u_____u I don’t know. My mind’s not working properly today.

  9. bowlero says:

    i recon that its not liquid, it could be come sort of display cup from the fromt of a shop.

  10. sco says:

    it’s gel!

  11. skeptic says:

    not milk?

  12. bill says:

    It’s vannilla pudding!

  13. bobby jo says:

    it is thickened

  14. Jerry says:

    maybe like gelatine milk in the top?

  15. JT says:

    That or it is yogurt.

  16. Jack says:

    It’s a solid block of somethin white i think?

  17. Dood_25 says:

    i dont think thats real milk

  18. SJK says:

    Simple it’s not milk. probably a yogurt… the video clip did not show Sammy pouring the milk into the glass. thus, we can only assume that it is not a liquid form of milk.

  19. maco says:

    Not milk? Something like white paint, or milk with gelatin added?

    Looking at the video, the liquid does move when tilted, just not very much…

  20. the_afterlyfe says:

    is the table tilted…?

  21. Falcifer says:

    I think its either that he has had his entire house tilted in three different directions (I.e, the glass is actually perfectly straight and the house is tilted) or that isn’t milk. Perhapse the ‘milk glass’ in the title only refers to the glass itself, not its contents…

  22. ACE says:

    no, it’s not frozen

  23. Mandy T. says:

    It’s curdled milk.

  24. ACE says:

    no, it’s not frozen

  25. Mandy T. says:

    It’s curdled milk.

  26. hrmmm says:

    maybe its glue instead of milk????!!! o.O


  27. outsidethecircle says:

    that thing is not milk. It could be custard or puding or something like that…

  28. Quinton says:

    I think its jello or something like that. Watch the video and you can see it jiggle!

  29. odin says:

    maybe it’s some really thick yogurt or sumthin…

  30. TJ says:

    is it buttermilk?

  31. Daniel says:

    I’m assuming it’s not milk at all. I’ve seen plenty of fake liquids in my time, things pretending to be water or soda, for example. This could just be some solid white substance.

    I can’t get the video to work, so I’m not sure if I’m missing out on anything. It’s also quite likely the milk is frozen (if it’s in fact milk).

  32. Night_Hawk says:

    After watching the video, I think there’s some kind of covering over the top of the milk. If you look carefully you can see that the milk still tries to pour the way the glass is angled, but there’s something stopping it.

    Cool illusion nonetheless.

  33. Luci says:

    It’s not milk it’s glue

  34. >&*gemma*&< says:

    omg thats s0oo not pure milk it is a jelly texture u almost will have to be soo dumb to not notice that go watch the clip

  35. Cefn says:

    He must be spinning around.

  36. Got Milk?? says:

    Because I’m fairly sure he doesn’t. The liquid in the cup seems a bit too thick to be milk. Though it surely is a liquid as it moves when he places it down on the table. Either that or a solid suspension in liquid. Also of note is the fact that the liquid inside the cup does in fact move as he tilts the cup. There is just a film on the cup which makes it appear that it isn’t. What does everyone else think?

  37. coolio775 says:

    is it jell-o?

  38. Byron Sanchez says:

    Weird. No guesses here. Best thing I could think of is that it has a transparent blockage… :/

  39. sammyg in the hizzie says:

    is it glue????

  40. koolal says:

    it is frozen and if you can not tell then you are stupid

  41. John says:

    I think my glass of milk would do that if I left it out for a week too.

  42. killer bees says:

    im gonna agree with j, its gotta be frozen

  43. Josh says:

    Looks like yogurt. Is it?

  44. Thomas says:

    looks like yogurt…

  45. killer bees says:

    gotta be frozen or just ice cream

  46. Michael says:

    You can see the meniscus quite clearly. It can be seen to move slowly in the video, indicating the mixture is very thick. My guess is that a gelatin was used to thicken the milk.

  47. KLink says:

    That’s fake plastic milk with a little water on top of it.

  48. Forge says:

    Gelatin, I’d bet, or maybe Elmer’s Glue.

  49. Duh says:

    Of course its frozen can’t u see. if you watch the video it will become more clearer. the milk doesn’t even shake but that was a cool illusion

  50. Bobby says:

    Elmer’s glue?

  51. Paul says:

    candle wax… not really milk

  52. db says:

    It isn’t milk, it is spreadable cheese. I’ve bought some just like that – glass and all.

  53. Hi says:

    It curd not milk.

  54. Prakhar says:

    I think its yoghurt or really old milk.

  55. sammy says:

    no its just the way the camera is angled

  56. Jun Ting says:

    i’m thinking it’s jelly?

  57. Nick says:

    I think it’s full of glue, not milk.

  58. Josh says:

    it looks like yogurt or something

  59. Me, just me and me only says:

    thats my guess, or its some other substance

  60. jonno says:

    Maybe the table is on an angle, with glass actually being held straight up.

  61. Nick says:

    Is it full of glue, not milk?

  62. bryan says:

    tricky huh? the truth is he is using a special powder that hardens any liquid in a matter of seconds. if you have a “magician” store near you they should carry it. its a fun joke to play on your friends with their beer!!!!!

  63. hello says:

    The milk become cheese… =D

  64. liveyourdream says:

    My bet is that it is pudding or yogurt.

  65. AKW says:

    It looks like glue…

  66. ziperingzap says:

    definitely looks frozen

  67. Arinu says:

    it is plastic milk they make for the kitchen sets for children. I am sure

  68. Joe says:

    This is easy. The glass doesnt have real milk in it but the fake plastic one that are shown in stores. For example in furniture stores they have wine glasses that spilled on a counch but the wine is fake

  69. arvind says:

    it is the candle thingee that they put

  70. Michael d says:

    I think its vanilla pudding because in the video when its places down it wiggles.

  71. asheeolee says:

    is it fake milk? lol

  72. JCC says:

    looks like jelly on the video

  73. Norm says:

    It’s not milk!

  74. Jason says:

    the milk was left out to harden, creating a layer which would make it seem that the milk is not moving with gravity

  75. delinquent says:


  76. Chris says:

    Looks like gelatin has been added to the milk. It seems to jiggle a little bit when it is moved.

  77. Riven says:

    It’s not milk. It’s glue.

  78. Frappo says:

    Here’s my theory. It’s not milk.(duh) Mix starch with water until it’s thick. Then pour into the glass, making sure not to drip it onto the edge (for appearance).

  79. Scooter says:

    It’s JELLO! :-)

  80. Lotus450 says:

    i think, the milk is spoilt… that´s the reason, why the door in the background is open :)

  81. lotus450 says:

    the milk is spoilt… that´s the reason, why the door in the background is open ;)

  82. Dex says:

    It’s a glass of glue or silicon

  83. tinman says:

    Maybe the milk has gone off and is completely solidified…

  84. Arty says:

    It’s not even milk..if it were milk and if it where frozen it would have another consistency…it probably is glue…plus he/she shakes it to fast to know it if it is anything other than glue…but it is defenitely not milk…milk moves alot when shaken and this is defenitly not milk!!!

  85. T. says:

    I think its glue. In the video, you can see it move around a little, but it’s much more viscous than milk. Cool illusion though.

  86. Lulu says:

    I think that the milk isnt real!

  87. hrr1971 says:

    Condensed Milk

  88. dunc says:

    i thought that at first but i think that it is gelatinus material… jello to be simple

  89. JuJuBee says:

    My guess is it is Elmers White Glue. I couldn’t see the video though.

  90. kdawghomie says:

    Ummm… it’s not a liquid.

  91. lulu says:

    it don’t look like milk to me! more like paint!

  92. EB says:

    it’s spoiled milk, or it’s mixed with glue.

  93. T says:

    The milk is moving (as shown in the third picture) but 1stly it is thick milk, maybe yoghurt or cream? Also, the milk is moving, but because the thick milk is sticking to the side of the glass it looks like the line of milk is straight arond the glass. a clever illusion, and if that is not correct, then please tell me how!

  94. Rich says:

    Ugh. When milk goes off it gets a thick layer of sticky smelly goo over the top that causes it to behave just like the milk in this picture. I hope that’s not how Sammy did it.

  95. sunDay says:

    is it spoiled

  96. g says:

    is it actually solid?

  97. e. says:

    you want that anti-gravity-milk too? just fill a glass of milk and wait …um…let’s say two weeks :D

  98. Don Huando says:

    I think there is very little milk there, most of the white is solid and only on the top there is milk.

  99. Makkhdyn says:

    Milk or Yoghourt ?

  100. hmmm says:

    well he only tilted the glass a little and the milk did tilt as well. i think it’s cause of the “remnants” of the milk on the glass that hasn’t flowed down yet. I’D LIKE TO SEE HIM TURN IT UPSIDE DOWN.

  101. Felix Upton says:

    has it gone off and turned solid?

  102. Keera says:

    It reminds me of some gel candles I have. I’m thinking the milk is nearly frozen or mixed with gelatine to make it solidify. There’s a bit of movement which makes me think it’s not completely solidified.

  103. l3utterfish says:

    i dont have a clue.. it looks like glue to me..
    where is the answer?

  104. ashleigh says:

    its PVA Glue isnt it

  105. Yor says:

    It seem yogurt

  106. Yor says:

    It seems frozen

  107. Yor says:

    It seems yogurt

  108. dnoyes says:


  109. dnoyes says:

    The bottom photo showes the “milk” being pulled to the lower side of the glass.

  110. minstar says:

    is the table skew?

  111. Justin says:

    Its yoghurt =)

  112. Catalyst says:

    I’d have to say it’s either frozen, refrigerated, or just off.

  113. m.shmitt says:

    it’s possible that a really fast shutter camera was usewd to take the pic as it was leaned b4 the liquid moved which also explains the “jiggly”surface on the last pic

  114. me says:

    computer wont let me see the video, so i may be wrong, but i think that the table/ camera are tilted, and the milk is really straight…..maybe the video shows differently?

  115. me, myself, and I says:

    listen it’s OBVIOUS because I’ve seen this jillions of times!!! The table is tilted and the glass is straight!!! no glue!!!

  116. lotus450 says:

    the milk is very old and thats the reason why the door in the background is open…

  117. Lotus450 says:

    the milk is very old and thats the reason why the door in the background is open…

  118. Girl7 says:

    its painted on the glass

  119. aeuh says:

    Its yogurt, milk turns into yogurt like this when you leave it outside and add yeast…
    Trust me , we make yogurt to eat everyday like this

  120. I am me says:

    I think it’s mixed with gellatin to make it thick. Also, all the people who think its frozen milk, you’re two things, dumb and wrong. When milk is frozen the fats in it clump togther and make it look yelloe, the stuff in the glass isn’t yellow, duh.

  121. zebe says:

    It’s something that dries to form a solid; and it just dries pretty fast.

    glue would probably work.. preferably a super-fast drying one.

  122. Duhh its that hottie x3 says:

    its condensed milk or milk mixxed with gellatin

  123. Sammy Salter says:

    It IS milk. i know. i did it.

  124. MOON says:

    He is around the earth, near the moon

  125. Splooshiba says:

    i go to school with sammy, and like he says “It IS milk. i know. i did it.”

  126. Bob Moon says:

    You could, of course, just use a clingfilm (seran wrap or whatever it is you Americans call it). Pop it on, heat it up to mould it. Job done. Liquid’s movement is then limited.

    If you look at the video, the distortion around the top centimeter of so of the glass seems more than a video atrefact.

  127. Anonymous says:

    It’s GLUE! I’m so smart!
    It has been left out to sit for a certain amount of time to get it to the right consistency.

    The liquid is milk.
    The house is on a hill and is not build vertical. The same with the table.

  130. Mark says:

    Maybe there’s a small bit of glass or plastic or cling film covering the liquid so it doesn’t fall out.

  131. Nathan says:

    Due to the reflection on top, and the shade near the top of the cup in the pictures (I couldn’t get the video to work:-( ) there is a thick piece of plastic that goes down about an inch into the cup, the cup is painted white and was always from being bought, there really is not much milk at all, but an elabrite set of mirrors on the inside, causing there to be a projection of it sloshing around slightly in the video (or so I understand) so it jiggles, but not enough to either hit the mirrors or the plastic, therefore, the illusion, hologramic projection.

  132. Anonymous says:

    i think its just the angle of the camera and the table and everything else is just not at a flat surface!

  133. Elliexx ANIMALS ROCK!! says:

    its probably not milk.
    but once, wen we were in Florida, my brother had a bottle of water and quickly turned it upside down, and then upright agen. he might hav just quickly turned it over and then upright. i dunno. but i couldnt get the video to work either so maybe thats y i dont no wat is causing it.
    cleverly done anyway!!

  134. Anonymous says:

    its ooblek you mix corn starch (or somthing like that) with water and when there is heat it liquifys but if there isnt it is more of a gelitin or glue

  135. Michelle says:

    if you can even get through all those posts about it being glue? and pudding, or yogurt, and curdled milk??

    im sorry idk what kind of pudding or curdled milk YOU’VE been eating, but it doesnt look like that.

    obviously as one Michael said “mixture is very thick. My guess is that a gelatin was used to thicken the milk.”

    its milky-gelatin
    it has to be. no other explanation comes close to the jiggle that it showed at the end when he turned it upright.

  140. cptmorgn1999 says:

    I believe it’s what’s called a “non-newtonian fluid”. It’s equal parts of water and ordinary corn starch from your kitchen.

    Here’s a link to a you tube video showing non-newtonian fluid:


    Could this be what it is?

  145. chiplover90 says:

    i think its frozen. definetly.

  146. rjnasher says:

    Correct me if I’m wrong, but it’s definitely milk… Seems Sammy is very lazy. Looks to me like he poured a full glass of milk and let it sit. And sit. And sit. The fact that it jiggles in the video shows that it is gelled, but not quite solid yet. After years of cleaning up after lazy kids, I knew what this was right away.

  147. Anonymous says:

    He’s spinning the glass, if this is real milk. Spinning/rolling the base, the lip of it not moving, so at an angle centripital (sp =/) force keeps it ‘flat’

  148. Llamalord says:

    the house is tipped, not the glass.

  149. Anonymous says:

    The surface on which they’re taking the video/photo is tilting, so relative to the true ground, the milk isn’t.

  150. Anonymous says:

    maybe he added glue.

  151. Anonymous says:

    no, there’s no mixture added to it, nor a gel, glue, or whatever. it’s an illusion, that photo was taken inside a tilted house. thats it, thats the explaination. in your perception, your brain recognizes it as a normal house.but its tilted at 25 degrees from the horizontal. its illusion is very strong as well. why dont you try one, build your own tilted house.

  152. Anonymous says:

    It’s not a tilted house, LOOK OUTSIDE! I bet it’s not milk either.

    Its obvious Yoghurt.
    Check out the third picture and its really clear.

    Love the site, and my iGoogle widget!
    Keep up the good work!


  154. Ze Head Biter! says:

    There’s a trick you can do with a glass of water that ends up acting the same way (I think), and I doubt milk has too much of a different density for it not to work- you make a small hole in the cup (with the liquid still in it), and then cover it up with your thumb. The pressure is supposed to make the fluid stay in place while you swing the glass around.

  155. Cassimo says:

    It’s Corn Starch mixed with water!! Really cool try it at home!!

    This is obvious that its either Not Milk AT ALL, or a spoiled milk, that isnt edible.

    I think that the whole thing is solid, or gelatin like, but has a little bit of thin white fluid (white shoe polish with water?lol), to make it look life its “Shaking” or “moving around”.

    I think We All know this IS NOT “ANTI GRAVITY MILK”.

    Its a 3/5 star illusion cause only like a little Puddle on the top was moving, but the rest was like fossilized tofu or something lol.

    Good AT triking people with the title and the first glance though.

    P.S.- ANTI GRAVITY MILK?! THats hilarious!

  163. Anonymous says:

    i know for 100% fact that it is curdled milk, i have had this happen to me when i left a glas of milk out over night 2 summers ago and i didnt have any air conditioning i went to dump it in the sink thinking it was fine and it did that exact thing where the top kind of bubles and u can tell that its liquid inside if the person holding the glass were to keep tilting the glass then the milk would breakthrough the top(it gets gell like) but its really groose when that happens, if you dont beleive me try it urself, leave a glass of milk out for a few days and if ur paitent enough you can do this “illusion” urself(all though i do warn you that it smells REALLY bad when its dumped out and ive learned to NEVER do that againand about not seeing the milk being poured its because it usualy has to sit for a couple days to get like that

  168. You all suck nuts says:

    Na its cornstarch or wteva the f*%# its called with water, the less water the harder it goes, its not a trick, its like gluing a ball to the roof and saying wow its amazing…….gay

  169. Sammy Salter says:

    yes its fake – you got to remember that this was initially an old illusion and most of the effect was got from the pictures, not the video. yes its fake, so what? did you really expect to see “real” anti gravity milk, as if such a thing exists.

    To the haters, its not meant to be real and blow you’re mind, you’re meant to think about how I did it, duh. To be fair, maybe it did look a lot cooler when you could see the pictures and not the video, as the video was only meant to prove that it was “really” milk anyway.

    All you have to do to achieve this affect is add some Knox gelatin mix to the milk. Some liquid would pool on top after setting giving it the almost liquid look. It’s jello-milk.

    When u pour milk into a glass, & drink some- it leaves an imprint on the glass. The imprint here is really strong so you can’t see through it!! If you look closely, the milk is actually moving, but the imprint is staying on the same place on the glass

    • enzovica says:

      i agree with yelsi, i think its imprint that left on glass and the color really strong so we cant see the surface of the milk

    maybe he put glass or plastic over the top. i think that cos the waters rippling. or he couldve put in jelly or yogurt or even frozen milk and poured a tiny layer of milk over the top. its possible.

    wow. i’m like 13 and i can solve it:
    It’s bad milk. if you leave it out long enough, milk will turn into this cheese yogurt thing that’s solid but looks liqued. that is how he did it. i dare any one of you to try it

    Its probably either cornstarch and water or partially frozen milk.

    This is clearly not milk. Either that, or its spoiled milk that has been frozen or left out too long. Show me a full video of the milk being poured into the glass, then tilted. I am very dissapointed.

    It is simply cornstarch andwater
