In my project I was trying to find out what battery lasts the longest. I will also try to determine if the cost of the battery has anything to do with the power it has.

In this project you will make a set of magnet rings to float above each other while their balance is maintained using a wood dowel. You will then examine the flexibility of the floating rings and propose uses for such a floating set of rings.
