Another wooden puzzle! This one was submitted by Joseph Lanius. Joseph said: “I noticed this today, and I thought you might like it. It’s a toy creation that anyone can make with some time on their hands, and it will impress people easily. The ball can roll freely up and down, but it can’t escape the wood prison, how did they get it in there?” I ask the same question. The only answer I came up with, was to curve it all from single wood block. Was I right? Now when you solved this one, go to next level. After that, solve how this guy managed to fit cork screw inside the bottle.
