Scientist of the Week-Bottle Tornado

This week we learned all about forces and pressure with our Scientist of the Week's Bottle Tornado. He showed us how to make our own tornado using plastic soda bottles, a rubber washer, water, and tape. Then, he explained how tornados work. We couldn't believe that tornadoes can twist at speeds up to 310 miles per hour. Wow!
