Sink Vs. Float

Sink vs. Float bottle
Don't let my ridiculous picture fool you. These bottles are easy to make and are great in teaching sink and float.

2-liter clear bottle
water-fill it 3/4 way full
small objects that sink and float. We used: paper clip, screw, small wood block, shell, clothes pin, pick-up stick, foam letters, coins, key, pom-pom.

There are so many great ideas of toys/educational toys to make with bottles. Here is one that would be great for halloween.
