I know that talking about your dreams is as boring as anything, but I have to tell you about one I had last night in which I was going to perform a magic show only to discover I had left all my props behind at home. In desperation, I found a bag of Ping Pong balls and developed a Ping Pong ball production right on the spot.
When I awoke, I realized that the theory was sound and workable. With a little bit of tweaking, I now have a new addition to my show as soon as I can buy the props and can afford some time to practice it.
All I really need is either two or twenty Ping Pong balls (depending which version I want to do), the specially constructed gimmick, and a drinking glass.
I love it when my brain works weird. ;-)
