OCEAN IN A BOTTLE
clear plastic bottle - a big soft drinks bottle is best
Some water
a few drops of blue food coloring
cooking oil
Directions
Fill one third of the bottle with water. Add a few drops of blue food coloring and shake the bottle until the water turns blue. Fill the rest of the bottle with the oil. Tilt the bottle from side to side. Since the water and oil don not mix the blue water will look like an ocean!
***For Tanner we talked about density. Very simple...some liquids mix but others do not because oil is less dense so it sits on top of the water. Shake it up and it will separate again. I briefly talked about molecules...he wanted to see one...hum!
