In maths we got a cup and DJ(our teacher) got a hammering type nail and dug it into a dozen or so plastic cups.Then we got a medicine, measuring cups. We got onto groups of two or three and one person gets the plastic cup and fills it up with water and then holds it over the mearsuring cup and the lets it drip for five seconds and then puts one of there fingers over the hole to stop the water dripping. We did that for a minute and some people got water all over them!
