There's really only one reason you should ever light another person on fire, and that's if you're a scientist who has a burning curiosity--and ready access to professional-grade firefighting and safety gear. If you happen to have a video camera on hand, that's a bonus.
This week on the Youtube channel Hard Science, the team lathered each other up with some fire-retardant gel, grabbed super-flammable magnesium, and set their arms ablaze with a blow torch. Just check it out in the video above.
How does it all work?
"The polymer that we're working with can soak up hundreds of times its weight in water," the team explains in the video. "Water has a really high heat capacity, which means it can absorb a lot of heat, so when you have all these layers of water... it forms this protective layer over the surface and makes it fireproof."
We echo Hard Science's warning that this experiment can be VERY dangerous and can cause serious burns -- DO NOT attempt it yourself!
