Plankton race

In class we received a bag with various materials too make an object that slowly sank to the bottom, the slowest time won. Me and my partner jokingly used the post-it note that was in the bag and it was extremely slow!! we let the post-it note dry and tested it. it was by far the slowest sinker so i wouldn't have changed it at all and i like how we won with the post-it note!
