Tetra KO is an innovative, fire-suppressing “gel” that has some real potential for fighting fires. The simulated real structure fire shows you how quickly the flames are doused and the “rekindle” is thwarted, the fire resistant ceiling at the end of the video is amazing. The one thing I don’t hear in the video is the cost of this fire suppressant, however, it is bound to be minimal when compared to the lives saved. If you want to see an interesting video about a potential fire hazard watch 9 Volt Battery Fire Hazard.
