Where did the sugar go?

We sprinkle sugar into two cups of water. One cup is warm. One is cool.

2

Warm water's tiny pieces zoom. Cool water's pieces are sleepy.

warm = zoomy cool = sleepy
3

A spoon of sugar goes in each cup…

4

Tap the warm cup — feel its pieces bump the sugar!

Tap the cup — see the zoomy pieces knock the sugar.

5

Same sugar in both! Which cup makes it vanish first?

Tap your guess!
