Via Washington Post:

At a certain frequency, the sound waves "separate the oxygen [in the fire] from the fuel. The pressure wave is going back and forth, and that agitates where the air is. That specific space is enough to keep the fire from reigniting."

guy uses chlorin e6 to get nightvision
- -

Science for the Masses used chlorophyll analog known as Chlorin e6 (or Ce6) to give healthy eyesight temporary night vision. This chemical is found in some deep sea fish and used to treat night-blindness. 

The group hypothesized the chemical could be dispersed into the eye and give a form of night vision. 



Via Mic:

Did it work? Yes. It started with shapes, hung about 10 meters away. "I'm talking like the size of my hand," Licina says. Before long, they were able to do longer distances, recognizing symbols and identifying moving subjects against different backgrounds.

"The other test, we had people go stand in the woods," he says. "At 50 meters, we could figure out where they were, even if they were standing up against a tree." Each time, Licina had a 100% success rate. The control group, without being dosed with Ce6, only got them right a third of the time.
