Our incredibly good-looking friends over at The Week have a scoop on a type of make-up developed by the army to withstand the temperature of explosions such as that of a roadside blast, or roughly 1,110ºF. This is around the same temperature as the end of a lit cigarette (fancy new fact!). The heat from an explosion effectively lasts only 2 seconds, yet the special make-up can last up to 15 seconds before first-degree burns start.
The secret is the ingredients. Instead of the fatty substances that are usually used in army face paints, the special heat-proof stuff is made of silicones and around 35% of DEET™ bug spray. Take a look at a demonstration yourself:
