This has been a summer full of “science projects”! My sons always ask me why why and WHY for everything. They have a passion for learning and a big curiosity of how their world around them works. They asked me to do experiments with water. I told them once that oil and water do not mix and they asked me why. Since I am not a chemist nor will I write them the chemical formula of them, I simply told them that I had to show them. This common experiment made them see that they do not mix, PLUS it was neat to actually “SEE” with colors the suspended molecules. To answer their question “mom is it going to explode?” I said we can make it become like a volcano. So we turned the lava lamps into a lava volcano.
- Alka Seltzer tablets
- Food coloring
- empty water bottles
But what happens when we add Alka Seltzer? Lava lamp!
Here is a picture of the one with mixed colors.
