Shower heads are usually not very interesting. Why not to take showering into next level with a cool shower head with built-in LED diodes which change their colour according to the temperature of the water! Don’t worry, no batteries are needed! The water flows through a very small turbine which generates electric power (LED diodes need only extremely small electrical current).
If your children feel bored during bath or showering, this simple and cheap showerhead will definitely do the job.
Awesome feature is that it changes colour according to water temperature. Do not get injured by hot water (which an electric shower can produce)
