Paddy Pump

A few weeks ago we were testing our paddy pump outside the classroom. We noticed when we were testing that the chain kept on slipping off.  We decided to tighten the rope.

We also had to fit a water wheel somewhere in the pump so we spent the afternoon designing where we would put the water wheel. We decided to put the water wheel under the pipe and cut a hole in the pipe and block off the end. After we cut a hole in the pipe we fixed the water wheel to the pump.

We had to get the Paddy Pump ready for the Sci Tech exhibition in the hall. We started to paint the Paddy Pump white and then went over it in truffula tree colours.  We had to work all day to get it finished and to get it up to standard.

It was an amazing time and everyone loved it in the Sci Tech exhibition and the Paddy Pump group are very proud of what we have made. Look up How to Make a Paddy Pump if you find it you should definitely try making one !!!
