Dr Bobby & Dr Jake the Scientists
This morning we filled up a plastic bag with water. We stuck spiky sticks and pencils all the way through, and we managed put 13 through without any holes and water coming out!!
We think it works because the pencil blocks the water coming out, and the air in the bag helps hold it in somehow.
