I first filled the jar with half water, half baby oil. We added a few drops of food coloring to the mixture, closed the lids tightly and watched to see what would happen.

of a 4 year old
There was some slight bubbling, but nothing major.
We agreed the jars were neat... but what could we do to make them react differently?
|We both liked the color of this jar the best.|
We went inside and looked around. We found some antacid tablets and decided to introduce them into the mix to see how the oil/water jar reacted.
We started to notice bubbles forming right away. It definitely simulated a lava lamp!
I made a really short little video demonstration of the reaction of adding the antacid to the oil/water mixture.
My son had fun with this project. It was a fun challenge to see what we could do with common household products, and it was even more fun to engage him in a science project. We think these would be fun with glow in the dark stuff inside. We hope to try this again in a few months with that idea.
