On the 15th of July we went down to the stream by our school. We made boats that had to carry 750ml of water but no-one put the water in. Me and Kyle boat broke when it hit a rock and the rudders got stuck on the rocks because it was so shallow. So our boat didn’t finish. On my boat I would improve the glue work it wasn’t the best when it hit the water it fell to bits but everything else was good.
