X-Men Ice Man Blasters

Inventor Colin Furze is back at it again, and this time, he’s created a palm-mounted liquid nitrogen blasters, turning you into Ice Man from X-Men, or so we’d like to think. Simply put, it consists of a “Cryopack”, which is filled with LN2, connected to a palm dispenser that’s activated at the flick of a wrist. He demonstrates his creation by freezing a plant, water and even a dummy’s burned head. Continue reading for a “making of” video.

Did you know that the temperature of liquid nitrogen can readily be reduced to its freezing point 63K (-210 °C; −346 °F) by placing it in a vacuum chamber pumped by a vacuum pump? That’s right liquid nitrogen’s efficiency as a coolant is limited by the fact that it boils immediately on contact with a warmer object, enveloping the object in insulating nitrogen gas.
