Behold Rulof Maker’s DIY Underwater Breathing Device

This tiny underwater breathing device is one of the coolest we have seen – and you can make it yourself!

This small device uses a water nebuliser – also known as a water mister – as the core of the apparatus.

It’s essentially a hand-held pump, which you normally use to pressurise water enough for it to spray on your face as a mist.
