Astronauts aboard ISS work on water that can make things burn without flames

The exotic substance, called supercritical water, is neither a solid, liquid, nor gas but rather a 'liquid-like gas'.

It is made by compressing ordinary liquid water to 217 times the air pressure found at sea level and heating it above 373 degrees Celsius, Discovery News reported.

Supercritical water rapidly oxidizes any organic substance it comes in contact with - in other words, it burns it, but without the flame part.

The water can aid in waste disposal, both in space and on Earth.
