Here's a fun one that the kids love:
Get a bowl of water, a salt shaker, pepper shaker, and dishwashing detergent (the liquid kind).
Imagine the bowl of water is a swimming pool. Now add some white sheep (salt), and some black sheep (pepper). Finally, add the big, bad wolf (a drop of detergent) and watch the black sheep swim away to safety!
I think this happens because the detergent spreads out a very thin film onto the surface of the water and pushes all the pepper out. The salt is only for effect/imagination purposes. To this day, this still fascinates me.
