Tornado in a bottle #SciWk2014 (Step 1: Energy and Forces)

On Wednesday we did an experiment. The experiment was called “tornado in a bottle “.
First we got a plastic bottle,we filled 3/4 of the bottle up with water. We then added a small amount of black current to make the water into a light purple colour. Once we did that we put another bottle on top of the bottom bottle. We stuck that on with duct tape. Once we had secured the two bottles with duct tape we flipped the bottle over and shook it so the water looked like a tornado while moving into the other bottle. It was a great experiment and I really enjoyed it.
