|Materials: 2 large glass vases, generic alka seltzer, food coloring, cell phone with flashlight app, glass casserole dish, vegetable oil (could be any oil), water, plastic dinosaurs, rubber duck.|
First I poured water in the big vase and put it on top of my make shift light box (cell phone with flashlight app on under a glass casserole dish).
|okay mom, I'm ready to go|
I poured vegetable oil slowly on top of the water. this part was fun to watch, the bubbles of oil caught the light and were very pretty. Then we added many, many drops of food coloring.
|In they go|
Next we decided to try the long rectangular vase. This time we added more oil and blue food coloring. The color took forever to make it's way through the oil.
|For. Ev. Er.|
