We have learned today on January 14th, 2013 more on density. We learned about the Seaperch, and how we will be making one towards the end of the year. We dealt with the controls and how to move it back and forward/up and down/spinning/propelling through the water, and picking up rings. We demonstrated today by making our own submarine with a drill and saw out of PVC pipes. By connecting a tube and filling it with water, we learned that by blowing into it that it will start to float. With just enough air it will stand straight up, also known as neutral buoyancy.
