I’m confused about the Strength Tester Optical Illusion. On the video it says the graphics are slightly different sizes, but on the graphic printout they’re exactly the same. The trick doesn’t seem to work this way. Should I just lengthen one of the graphics?
I have been doing this trick for years and my “smiles” ARE the same size. I show them together, the same size, now magically give the child the strength of his favorite super hero, now I have the child pick one and then he/she pushes that one and then I show it “smaller” I give the child the other smile and he then pushes it and now they are the same size (they always were). then I have the child use just his thumb and first finger and pull on one, it is now “longer”. He pulls of the other smile and now it is the same size. David Ginn sells a version of this trick.
I have twin little boys boys and they just keep taking turns making their piece longer than the other one.. It was so funny to watch
Thank you
