The coke bottle I filled half full with water and put a couple drops of blue food colouring in it. Then I put about 1/3 cup of oil in. This one even the girls enjoy playing with as they shake it around and then watch the oil and water separate. It has spawned some science discussion as they ask why the oil and water do not mix. (Although the answer is beyond even me, it has something to do with water being charged positively on the oxygen end, and negatively on the hydrogen end. Oil does not have a charge (it's neutral), so the oil does not mix with the water.)
So there you go. Some simple homemade toys that cost pennies to make.
