Of course it’s the fall and the days of summer are fast falling behind us but before you pack up the pool equipment there is one final thingy we want to show you. This is the Medusa pool light, a solar autonomous floating lamp for swimming pools. Toss one of these organic looking devices into your backyard pool and it will light up the water for your nighttime swims. The tentacles look to be made from fiber optics and gently twist and turn around in the current. The great thing about it is that since it gets all of its energy from the sun you never need to charge it up.
