The purpose of my science fair project is to see if food coloring in a homemade lava lamp will move faster in cold or hot water. This is good for society because you don’t have to waste money on a lava lamp when you can make your own. This has an importance to me because I used to have a lava lamp when I was younger but we could never afford one so I decided to make my own. When you buy a lava lamp you have to plug it in but, when you make your own you don’t have to plug it in for it to work, so this is really good for society by going green.
