Water Tower Builders

Last Monday we had a challenge to build a water tower. We could only use cardboard, string, ice cream sticks, cellotape and an ice cream container to hold the water. We had 25 minutes to build it then Mr A poured water into the ice cream container which needed to be at the top of the tower. We were looking at if the water tower was strong enough to stay up once the water was poured in and if the water stayed in the container. The water container needed to be at least half a meter above the ground. Once we did our experiment we discussed the shapes we used to build our towers and then why some water towers are built differently around the world.
