So I liked the chocolate melting idea. I will be using the chocolate you buy at the store that you can place into molds (to not be wasteful) and timing how long it takes to melt. The variables will be how many chocolate pieces and how much time it takes to melt on a medium low temperature on my stove top. I expect that the more chocolate pieces that I use the longer it will take to melt on the medium low heat on my stovetop.
