Joy is a 12-year-old Masai girl living near the Magadi lake in Kenya. This lake is very special. It's a salt lake and once in a while, it runs dry. The salt that was in the water, stays on the bottom of the lake, where you can easily scrape it off. Joy investigates the special characteristics of salt. She makes a necklace with beautiful salt crystals, uses osmosis to preserve vegetables and explains why you can never drink the salty water from the lake, even if you are very thirsty. That's a shame, because it can get very hot near Magadi lake. To cool off, Joy uses salt to make a bunch of tasty coconut ice-cream.
