Alex always loves doing a Science Fair project, even though it's optional. This year Mark came up with the idea of a Dry Ice Experiment. Alex did it with his friend Korey. It actually turned out really cool and they had a lot of fun with it.
You may remember in years past Grandpa has helped Alex. This year Grandpa was out of town but we and by we I mean Mark managed to pull it off. See Alex's other Science Fair projects HERE and HERE.
Also one of Connor's HERE.
