QC#25 – “Mad Science” Leidenfrost Experiment

DANGER: For demonstrational purposes only. Do not try this at home. The Leidenfrost effect is demonstrated using some “Mad Science”.

Project Inspired By:

“Drinking Liquid Nitrogen” http://youtu.be/R2f1ECjs9fA

WARNING: This video is for demonstrational purposes only. Although Liquid Nitrogen isn’t readily accessible to the general public, it should always be treated with caution and respect. At a temperature of -321F, it will start to freeze organic matter within seconds. Never drink liquid nitrogen. Use of video content is at own risk.

Project History & More Info:

To get this effect, I took a deep breath in, held it, then poured a small amount of LN2 into my mouth, and blew it out forcefully without hesitation.

Assuming that my mouth is approximately 98.6F and liquid nitrogen is -321F, there is a difference of nearly 420F. As the liquid nitrogen contacts my mouth, it is instantly boiled and vaporized, and amazingly doesn’t make contact with my mouth at all. The cloud you see blowing out as a cloud is caused from moisture in the air being condensed by the extreme, and sudden, temperature change.

There is a danger if larger amounts of LN2 are used, as it could quickly cool the mouth and cause tissue damage.

This footage was originally included in my “7 “Super Cool” Demonstrations with Liquid Nitrogen” video: http://youtu.be/KlAl5RHAAns, but was cut out due to some viewer concerns.

Presented in this manner, the footage is still accessible, but not implied to be duplicatable.
