The Washing Hands Sounds Good Soap Dispenser

The Washing Hands Sounds Good Soap Dispenser

During Covid-19 Pandemic, we have learned that the best way to fight this damn virus is to wash our hands often with 🧼 and 💧 for at least 20 seconds (according Centers for Disease Control and Prevention). And yes, it's true. It's a bit boring to wash your hands for 20 seconds.

But what if during those endless 20 seconds we listened to an epic song that made us forget about time?

Let me introduce The Washing Hands Sounds Good Soap Dispenser.

Maybe people think that the naming is too long, but I love it. And it sounds good. 😉

The Washing Hands Sounds Good Soap Dispenser is a little idea and a cheap DIY project that it's very easy to make.

The version 1.0.0 was launched to commemorate the Star Wars Day (May the 4th, 2020).
