The accompanying sketch shows a trick of removing a dime from the bottom of an old-fashioned wine glass without touching the coin. The dime is first placed in the bottom of the glass and then a silver quarter dropped in on top. The quarter will not go all the way down. Blow hard into the glass in the position shown and the dime will fly out and strike the blower on the nose.
I’ve tried to learn this trick a lot of times, but I always failed, and I think I’ll finally be able to do this trick. The science behind this trick is relatively simple, and that’s what irked me in the past.
