This is an awesome way to bring excitement to your science lesson! Most grocery stores have all of the ingredients needed. I like to do this in a place where id you do spill , it's easy to clean. Tips, make sure you start with a container that will hold all of the liquid in the experiment. Also we used flat round LED lights to illuminate, I found on Amazon.com. These were easy to turn on and then sit the vase on the top. The kids called them lava lamps, or Radioactive lights, LOL!
