Today Meena and I made an electromagnet with wire, a nail, and a battery. First, we had to go and measure the magnetic stuff without any wire wrapped around the nail. Then we had to do it with it wrapped around 3 times, 6 times, 9 times, and so on and so forth. We had gotte to 9 winds and I accidentally deleted it ALL!!! Good thing it was the end of class anyways.

Heat Sheilds
Today Rhys and I attempted to make a heat shield. We rolled up a ball of tin foil then put another layer on it and made it look like comet. It lasted for 50.63 seconds. Not too bad for a first try!!!
