We all know how a fire extinguisher works, but what if you could quell the flames with nothing more than thumping bass? File this one under one of the coolest class projects ever.

George Mason University students Viet Tran and Seth Robertson spent $600 of their own money to build a prototype to prove it was possible to use sound waves to put out fires, and their little device could potentially lead to tech that might save lives in the future. The kit consists of a 20-pound shoulder pack to generate sound waves, and a canister to direct the waves.

According to the duo, low-frequency sounds like the thumping bass in rap tunes seem to work best to put out fires. The team tested the equipment on grease fires (which are extremely dangerous and can get worse if you douse them with water). It could also have applications in spacecraft, as a safer tool to extinguish accidental fires. Tran and Robertson have already patented their design and hope to take it to market within the next year.
