Not just a trick, but a full 9-minute routine!
A spoon visibly bends, and is handed out (you heard right -- handed out) for examination.
Then, offering to illustrate how it's done, you draw a picture of a spoon and have a spectator sign it.
Now, the picture of the spoon bends! This is then given away as a freaky-deaky souvenier.
Comes complete with custom made props and detailed instructional DVD.
If you've seen Thom perform live, then you know that he ALWAYS includes this routine.
