Simple, Effective Physics experiment...?

I have to design a Physics experiment for school. I am in year 12 (the final year of high school), so it can't be too easy but I want something that is easy to set up and easy to record results on. It also needs to be quantative. Any suggestions? I was thinking something to with the Leidenfrost Effect,... show more I have to design a Physics experiment for school.

I was thinking something to with the Leidenfrost Effect, because my teacher said that could work, but I am having a lot of trouble coming up with an experiment, so any suggestions would be greatly appreciated!!

Thanks.
