Cool faucet waterfall thing for kids.

Flo. I will buy one.

Combining multiple functions into a single device, Flo provides a simple solution to several bath time challenges. This unique product diverts the flow of water, creating a gentle waterfall, while providing a protective faucet cover to help guard against injury. Flo also functions as a bubble bath dispenser.
