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."

Kids in Northern Ireland are Living the Dream; Minecraft is Free in Every School

Specifically, secondary schools across Northern Ireland are being given copies of MinecraftEdu, a version of the game designed to be educational.  This initiative is expected to bring Minecraft to 50,000 kids, and will be used to teach everything from art to history and computer coding:

Last week we worked with Artichoke and The Space to recreate, in Minecraft, a version of Burning Man artist David Best’s ‘Temple’ in Minecraft.

The real world Temple was a 70ft structure in the city that was ceremonially burnt. When we took it into the schools we were able to give young people a chance to create their own versions of the Temple, working alongside the artist. We’ve seen Minecraft being used to teach everything from coding to physics but I think that there’s a real opportunity to develop more of these kind of creative projects too.
