Bath Science

Here are a few sciency tricks that we can do at home in the bath: we can get water to stay in an open bottle turned upside down, we can get water to stay in a yoghurt pot with just a sheet of card and we can get a ping pong ball to stay in an upside down open bottle of water.  We know why all these things work too!!!

The air that is under the sheet of card or under the ping pong ball holds the card/ball in place.

We can get the ping pong ball to dramatically fall from the bottle if we blow away the air under the ball, causing a vacuum to form and allowing gravity to pull the ball down.  We all got a little splashed but it was so much fun that we will practise this in the bath at home!
