George Mason University students Seth Robertson and Viet Tran believe they've found a way to put out fire with—get this—sound. But before you grab a Beats By Dre set and a matchbox, let's be clear that it's not quite that simple.
Esssentially, the duo created a prototype that emits low frequency waves, akin to the "thump-thump bass in hip-hop." When in the 30 to 60 hertz range, these sounds can separate oxygen from fuel. This means there are zero chemicals or other aids in the prototype. It really is just sound!
As of now, the guys have only used the prototype to put out small fires, but if things progress, this invention has the potential to save water and end the usage of fire extinguishers altogether.
Watch the magic for yourself.
