It’s not often that I stumble upon an illusion I can’t figure out. What you see below isn’t some team building assignment, but rather an optical illusion. I assure you it’s not manipulated. This is really puzzling, don’t you agree? Your previous assignments were much easier you have to admit. Like the time when I couldn’t spot that easy baby illusion. Let’s brain-storm this one. How did it took place? After this you might want to solve some easier examples, and let your brain relax. The ones I’m referring to are impossible bottles and cube toy.

Hammer and Ruler Puzzle

    alright im confused!

    is anything nailed down or is it a matter of angles?

    Those r tight. so fun to do with paperclips and penils. 1st comment.!!

    I think I figured it out I see two possible nails one on that part on the hammer that has a name but I can’t remember it at the moment and the other on that string or wire thing.

    Wow. Run-on sentence.

    All I can think of is that they somehow managed to hang the hammer perfectly, so it sags in such a way that it pushes one end of the ruler up, pushing the other end down, into the table, and therefore holding itself up… it’d have to be, like, a titanium ruler though.

    (I have no idea if that’s even possible, but it’s all I could think of. =P)

    the weight of the hammer is centered below the wooden board. This is similar to those single wine bottle holder (e.g., http://www.wineintro.com/products/racks/balance.html).

    It’s not an optical illusion. It’s a trick. A hammer, ruler and hair tie will balance just like that without effort.

    Very cool though!

    This is simple. It is EXACTLY as it looks. You can try it at home, and I assure you it will work. The center of gravity is BEHIND the end of the ruler. There is absolutely NO trick – everything is just like you see it.

    I think we are looking down at the hammer and the ruler…and the board of wood is standing on its side and proped up by something out of the frame…..

    its just physics, its just perfectly balanced the head of the hammer counter balances the weight of the ruler

    omg u hav to be one think prick not to get this within 5 minutes look where the eavy part of the hammer is its under the table makeing the bit on the table the heavyest but becuse the other end is the longist does mean its the heavyey think pricks

    When I were a lad we learned this stuff in primary school! And we didnt need bad language or insults to help others learn! Centre of gravity trick – simple but effective & useful if applied to ‘real’ life!

    I KNOW THIS ONE!
    the weight of the hammer pulls the ruler down, but the hammers handle is up and thus pushes the ruler up!

    I hope i dont make a noob of myself with somebody proving me wrong. but for all i know it could be, i inferred this in a matter of seconds.

    its like those birds that balance on the tipe of ur finger, the center of gravity is lower than ur finger or in this case under the table

    its REAL. the heavy end of the hammer is keeping the ruler on the wood while pushing up on the other side. theres no trick, i tried it it works. =] I WIN!!!

    its upside down!.. the hammer is anchored by a nail thus it holds the ruler NOT the opposite.

    It’s clearly just a matter of balance/center of mass.
    I swear to God, next you’re going to be posting a movie of somebody doing the moonwalk and saying it’s an optical illusion.

    HOW DOES HE DO IT? IS IT ROPES AND PULLEYS?

  20. Pouch says:

    oh! i do something similar to this at dinners with 2 forks and a toothpick… its all about balancing! kinda like this:

  21. Zero says:

    I just tried this and it works. No Illusion here, just physics. The head of the hammer has the most mass, the ruler and handle have a larger “moment about the axis” or more leverage. So they balance.

    hey, that piece of plywood is floating in mid air!…so is the ruler. maybe like the plywood, something is holding the ruler up? i think the bow in the ruler almost “rules” out that being on the floor

    This shows the effectivness of the idea of the center of mass. All objects, no matter how strangly shaped (like above), has a point where all the weight is “located”. By located I mean, the entire object can be treated as if it exsist at the vary point at which all its weight is balanced. This idea is used widely in the field of engineering. A common experiment is used with two forks, a toothpick, and a cup… good times…

    It’s the same type of effect as the spoon/fork and match stick on the side of the glass trick. Its all to do with weight and counter balance. No nails, no glue.

  25. Anonymous says:

    the head of a hammer is heavy, pushing the centre of gravity to the left of the edge of the table.
    It’s no illusion, it’s just physics.

    well i think the ruler is glued to the table with super glue and the other side of the ruler is being held up with invisible string so it makes the hammer stay on.

    I think the picture is upside down …

    Its something to do with gravity isnt it!?!?!

    This is awesome. I teach science and we do this experiment. Also works with tooth pick and small spoon. It all about balance and centre of gravity. I loved it! Thanks.

  32. G says:

    its called physics, and its cool

  33. ahmadazwa says:

    This is no trick, it’s absolutely as it is! I’ve tried it: look at mine on flickr: Here

  34. Stryker says:

    This is a trick based all on balance. I did this at home and it worked. String hammer and a rulerput it together as it is shown it may take a little adjusting string length, but it does work.no nails or photo tricks required.

  35. Anonymous says:

    The wieght of the head of the hammer works with the perfectly possitioned piece of string to create a seesaw effect that is sufficient enough to hold the ruler and the weight of the hammer, hence the ruler is bending up.

  36. Anonymous says:

    hah, the comments are hilarious. I mean, it’s obvious that an invisible alien from planet zeta is standing right below the ruler and is holding it up! I can even almost kinda see it! Come on, people!

  37. Anonymous says:

    This is a classic case of physics. The head of the hammer has more mass than the handle of the hammer and the ruler have combined. The center of mass of the entire contraption is to the left of the edge of the table, meaning on the table. Therefore it cannot fall.

    Ok people
    its called phisics
    its the Center of Gravity (CoG)
    in easier ways its why a jeep with a lift kit and huge tires rolls so easy
    My 6th grade science teacher showed me this (i was amazed at the time)

    This is mearly physics and balacing forces. Why get yourself is a state over this.

  42. Erik... the 12 year old says:

    its so simple, all it is is the hammer head pushing weight down while the bottom of the handle is putting force on the ruler at the same time.

  43. zach says:

    i see it

    the heavy end of the hammer counter balances the other end of the ruler

    The weight of the head of the hammer balances it out.

  47. Anonymous says:

    I dont think there are any nails involved. Its to do with the center of gravity. Now the ruler is balance at the end of the wood. The strig causes the end of the hammer to be pushed against the ruler. This makes the ruler and hammer act as one object. If you notice the heavy part of the hammer is left of the end of the ruler. This moves the center of gravity to below tip of the ruler and thus stopping it from falling over. Sorry if I’ve explained this badly but im not a scientist.

    Basic cantelever physics I think you will find. Used a lot by Frank Lloyd Wright – but good for the brain!

    looks like the handle part of the hammer is nailed to the wall.

    Omg that’s awesome. I wonder how people do that stuff.
