Water Rocket launch






















































































































































___________________________________________________________________

This morning teacher took us over to the pitch to try out the new water rocket. We weren't sure what to expect but we were truly AMAZED at the results!! First we filled about a quarter of our plastic bottle with water (air occupied the rest of the space!) and then we attached the bottle to the pump using a special valve. Then we began to pump more and more air into the bottle (it was hard work!!) causing huge pressure to build up. Eventually the pressure built up so much that it popped the valve out and the rocket flew up into the air. We had to run far and wide to catch the rocket and couldn't believe the distance it travelled. We really enjoyed this activity.
