Designed to teach children healthy hand-washing habits, SquidSoap works by applying a small ink mark on a person's hand when they press the pump to dispense the soap. The ink is designed to wash off after the hands are washed for about 15 to 20 seconds — the time recommended by most doctors. SquidSoap is fun for kids and makes hand washing more like a game. Also, the very stretchable squid toy is a blast to play with and will provide hours of entertainment.
