Santa's Snow Sack by Jonas Haag

You present a Santa hat and turn it inside out so that the inside is completely empty. Then you turn the hat right side out again, flick it once, and out of the newly empty hat you get a white silk scarf! The scarf now goes into Santa's sack of presents. The sack is completely green inside and out, which you also show. The white scarf symbolizes the white snow. And what happens to snow that IS heated? That's right: it melts. So you rub the sack of presents, turn it inside out, and the resulting frictional heat causes the scarf (the snow) to disappear!
The whole process is repeated three times. In reality, the snow doesn't actually melt; it just becomes invisible. If you blow on the bag once, the snow becomes visible again. You try it out and turn the bag inside out. The snowflakes are still gone, but the inside of the bag is no longer green, but completely white on both sides!

• Very popular effect with children!
​​​​​​• The game includes the hat, the green bag and three white 20x20cm silks.
