This homemade water wheel is easy to make and works so well, arguably even better than the version that Travis put together from a recent Kiwi Crate.
The set up was largely a grown-up job, as it involved hot glue and scissors. Trace an empty ribbon spool onto a plastic lid (such as from a non-dairy yogurt container). Cut out the plastic circle and hot glue onto the spool.
Pierce a hole through the center with a push pin.
Now use plastic condiment cups as the spokes of your water wheel; hot glue these around the spool as close together as possible. Insert a skewer through the hole you made with the push pin, then slip a straw over the skewer for comfort.
Time to spin!
We headed outside and used a recycled water bottle to pour water over the contraption. The water wheel worked so well, even though I had worried gaps between the condiment cups might mean poor performance.
