00:00The flame my propane torch generates is almost 2,000 degrees Celsius, and I can hold it against
00:06a tile in my hand for several minutes before it becomes uncomfortable. As soon as I turn the torch
00:12off, the carbon foam is cool enough to touch almost instantly because carbon is very good
00:17at dispersing its heat as infrared light. 40 grams of flour, then 20 grams each of cornstarch,
00:24powdered sugar, and baking soda, and give us our final result, an extremely heat-resistant
00:31putty which can be used as-is or dried into solid tiles.
