Dustin had to do an experiment for Science this year. He decided to use nails, stripped copper wire, and batteries to make magnets. He then tested different gauges of wires, to measure how many paper clips the different gauges would pick up. It went pretty well overall, though I should say the batteries do get very warm when hooked up to the wire, and if you let them get too hot because you are almost done testing, they will explode!
Trust me.
