It’s going to be a hot summer. One of the best ways to cool off is by jumping into a natural swimming pool like this one. This pool is free from chemicals and is safe for pets and wildlife. It was made for a fraction of what a traditional pool costs. David Pagan Butler is the expert of natural swimming pools. He offers courses and instructional DVDs on how to do it yourself. David likes to minimize resources by incorporating reclaimed materials and making filters from reused household objects and domestic plumbing.
