Final blogpost on the waterwheel:
Our waterwheel is able to function properly because of the way our wheel turns effectively and when water starts to hit it, it runs very efficiently. Our straw where the water comes out of was originally not strong enough to keep the wheel moving smoothly, so we had to change it out for a larger piece of plastic pipe. Once that was installed our wheel was able to keep turning continuously, under the pressure of the now stronger stream of water.
In terms of improvement, we could have glued the sticks of the wheel better into the bottle lid but we were at high risk of burning ourselves to we had to be careful. If we had noticed that a small straw would not work well enough, we could have swamped it out for the tube before we glued it on. However, we did not foresee that our small straw would not be able to generate enough water pressure for the wheel to turn efficiently.
This product did not negatively affect the environment because we used recycled materials to build our waterwheel.
