Turn water into ice in seconds – Magic tricks
Everyone knows that water freezes at 0 °C – or does it? When water freezes, it needs a nucleus in order for the solid crystals to form and become ice. Water is typically full of particles and impurities which have no problem kicking off the crystallization process. However, purified water by definition doesn’t have those impurities. With nothing for the water molecules to latch onto, purified water can be supercooled as far as -40°C.
What You Need:
Pitcher of water
Large plastic cup (not clear)
1.Put the dry sponge securely in the bottom of the cup so it won’t fall out if you turn the cup over.
2.Put the ice cube in the cup on top of the sponge.
3.Now get an audience…
4.Pour a small amount of water into the cup.
5.Say some magic words and turn the cup upside down.
6.The ice cube will fall out but the sponge will have soaked up the water!
