Interiot from digg said, “Hair spray is flammable. With so little oxygen for such a short burst will cause anywhere near the amount of pressure or heat that something like gunpowder would. And it’s not like there’s a big risk of even setting the cardboard on fire because the cardboard is too thick and there’s not enough oxygen in there. Cardboard is perhaps one of the safest containers. If it does rupture, bits of cardboard flying at your skin will cause far less damage than PVC fragments or something like that.”
