You present a Santa hat and turn it inside out to reveal the inside perfectly blank. Then turn the hat the right way round, snap once and you'll get a white silk handkerchief out of the just empty hat! The cloth is now placed in Santa's gift bag. This is completely green from the outside and inside, which you also show. The white cloth symbolizes the white snow. And what happens to snow that WILL be heated? Correct: it melts. So you rub the gift bag, turn it inside out and the cloth (the snow) is gone due to the frictional heat generated!
The whole process runs three times. In reality, however, the snow does not melt at all, it just becomes invisible. Now if you blow on the bag once, the snow WILL become visible again. You try it out and now turn the bag inside out. The cloths are still gone, but the bag is no longer green on the inside, but completely white on both sides!

• Effect much loved by children!
