The children decided to build a swimming pool!

First they built up the sides stacking bricks one on top of another and looked at how stable the sides were. Miss Bonner showed the children how to build the walls by overlapping the bricks. The children, however, didn’t think this was the right way to do it and continued their way using mud as the cement to hold the bricks together! Once completed they added water, but the water started coming out of the gaps so they tried putting other objects in the spaces. As this didn’t stop the water coming out they tried Miss Bonner’s idea of building the walls by overlapping  the bricks instead and found a liner to go inside. Finally they filled it with some water to see if it stayed in there.

Guess what happened?
