Play-Powered Pump!
OasiSaw is a clever pump system that utilizes FUN to source ground water! Modeled after a seesaw, the design harnesses the energy created during play to not only pump, but filter water using a carbon nanotube filter. After building up a fun-fueled sweat, they’ll have plenty of fresh, clean water to quench their thirst, with more to share!
