Designing Rockets.

This week at Stem Club we started designing rockets in pairs which hopefully in a couple of weeks when we've built them we will be able to fire. Mr Chew showed us the one he had built. It was really pointy at the end and quite thick. It was green and silver and had the words 'brigshaw 1'. It had a small cylinder attached to it which went over a thin piece of metal in a upright position. Mr Chew then showed us the parts of the rocket and said we could touch and hold them . He then asked in pairs to create a detailed drawing of the rocket we'd like to build with all the measurements. Me and my partner decided on a long thin rocket with a pointy end. Others decided on a thick body with a curved end.
When we'd finished designing our rockets we went to the back of the P.E block. Mr Chew said he was going to fire his rocket. A crowd of people gathered including teachers and we counted down from 10. He set it off and it went vertical direction which was good as it went about 100m. However a parchute was supposed to come out and float down. It didn't. Mr Chew showed me the parachute after and he said the reason the parachute didn't come out is beacuse the gunpowder core was so hot it burnt through the insulation. He said that if he did it again he would have to put more insulation in preventing the parachute burning.
