Anybody own this? I bought one recently and it is quite cool. I've tried it and the effect is very strong. Borrow a coin, hold it in your hand while the other hand reachs for a lighter in your pocket. Light the lighter and pretend and heat up the coin. Ask spectator to touch the coin to see if it is hot and ask her to hold on to it tight. You slowly rub your hands and reveal the coin, ssttttrrettcchheedd!!
It appears that you just melted the coin!
