Liquid Nitrogen Biscuits No Danger

Soak the biscuits in liquid nitrogen, and it will "smoke" in your mouth!

Although the temperature of liquid nitrogen is extremely low (-196 ° C), at room temperature (considered 25 ° C), such a low temperature cannot exist for a long time, and the biscuit will heat up rapidly just after it is taken out from liquid nitrogen. When you put it in your mouth, it will be at least a dozen degrees below zero, and it will not cause frostbite.
