These NASA engineers found a way to put out fires using sound waves!
The method, developed by Sonic Fire Tech, uses deep bass frequencies, too low for humans to hear, to literally shake the fire apart.
The sound waves, officially called Infrasound pressure waves, knock oxygen molecules out of the way before the fire has a chance to use them for combustion.
They can extinguish fires from up to 10 feet away, and even prevent fires from starting in the first place.
They do require a special kind of speaker, as most speakers can’t produce these deep bass tones at the high pressure required to affect fire, so don’t try just blasting some Drum and Bass if you start a fire at home.
They’re now developing ways of deploying the sound waves through ducts in buildings, to prevent apartment fires for example, or even attaching them on drones or to trees to prevent wildfires.
Putting out fires like this would save resources, and mean much less damage and clean up, as no water or chemicals are needed.

I knew raves would save the planet
I wonder how animals perceive it!
Its so strange seeing actual good news these days
For anyone interested in more context/history about this idea: Charles Kellogg first put out a fire with sound publicly in 1926. DARPA and Myth Busters both did it around 2008. Students from George Mason made a similar device in 2015.
This innovation doesn't resemble any of theirs. It can put out bigger fires from longer distance, is scalable and can be used in practical applications. But, it can be argued it does the same thing as all of the preceding examples in some sense. TLDR: This was first done in 1926 on a much different scale.
Love your work Sam, the research and story telling, positivity. You are a much needed person in the world, big love to you!
Incredible. Let's keep funding science
Wow...Thats really is a cool idea... Hope to see it soon implemented all over the world.
Science is amazing!! 🙌🏽 🔥
Woahhhhhh
How amazing!! Love learning from you man 🙌👏
Wow 🔥📢
🤯🤯🤯
This is so cool! Fo you know if the frequency damage human ears even if not audible to us? Do these fire fighters need special headphones to protect their ears whilst fighting the fire? I hope they do research on this too! ❤️
This is SO cool!!! science nerd here. I’m living for this❤️❤️
This is AMAZING
