Summer is my favorite time of year. I love being in and around the water.

Throughout college I taught swimming lessons. Some kids could float while other could not… even after learning the proper technique.

I did not know it at the time but, this can all be explained by learning the principle of floatation, known as Archimedes Principle.

John Ingalls, a marine engineer who works for the Navy and his son Cobb, helped us to learn why things stay afloat.

We got to see a Cardboard Boat Race in Lunenburg, MA held by the local library.

Making your own boat and racing it looked like a lot of fun!! Many thanks to all involved!
