I found a bunch of these different kits from Toy Smith and I have to say I love them! This one in particular is Toysmith 4 M Clean Water Science #4572. Clean water is something much buzzed about due to recent natural disasters and over use. The Clean Water Kit is great for in class experiments or even at home to teach your children about the importance of clean water. This kit is also good for traveling so you can learn incase of emergency how to make clean safe drinking water.
Help to save the enviroment. Learn the science of cleaning and reusing dirty water by conducting interesting water purification experiements. Build your own water filteration and desalination plant at your table top; disinfect water with solar power and more. It’s a cool water science experimental kit. This personal desalination kit demonstrates the scientific way to extract salt from sea water. Contains a plastic filter system, active carbon, sand, rock, filter paper and instructions. Just add a water glass! For ages 8+.
