One of my favorite things to do is to show magic tricks to kids at family weddings, reunions, etc. If they seem interested, I'll take a kid aside and explain that I will show him/her how the trick works and give them the gimmick if they PROMISE to practice and perform the trick for someone else sometime soon, and of course, NEVER tell the secret. I love little inexpensive items like this for that purpose and I gave away my cheaper "blue" version in such a scenario. This one is much nicer (and a bit more expensive) and I think I'll keep it for myself!
