Light house challenge

On Thursday the 19th of March 2015 the years 4’s did the lighthouse challenge
The rules
-your lighthouse has to be 100 centimetres tall
-1 metre of masking tape
-you must make the tower in 90 minutes
– your tower must be able to stand by it self
-your light house needs a platform of cardboard on top of a to hold a jug of tennis balls
-your lighthouse needs to be stable to pass the 30 second fan test
-you need to work as a team

My group worked good because we got the tower built but it would of been better if we we had a girl because it was all boys, were being a bit silly. The problem was that we did not choose.
