Radioactive Canister Soap Dispenser
Another bathroom idea for kids (or science-lovin’ grownups), I present a soap dispenser that looks like a Radioactive Canister. It features battery-powered LED lights that pulse when the pump is pressed.
This is your standard pump design, but I can see this being a fancy wall-mounted dispenser (with a hands-free sensor). Also this idea could be given a Teenage Mutant Ninja Turtles makeover.
I could see a parent telling their kid that washing hands with this will give them superpowers.
