LINK quote [The illusion with money bills isn't new as well. But the combination of all these previously seen effects looks awesome. See how many celebrities can you recognize, but please post only two per comment. The genius of the author can be seen through resemblance of the bills he used with certain celebrities.

Head in a Jar

quote [The Head In A Jar is my all-time favorite prop and is 100% original! I came up with the idea by accident when I was looking for some rubber spiders to use in the jar. Wouldn't it be cool to put a head in one? But how would you get a rubber head in through the tiny little hole in the top? Then it hit me! Who said it had to be a rubber head anyway? It is supposed to be an illusion after all! Who says it has to really be three dimensional, as long as it LOOKS three dimensional, right?].
