It's been said that in an emergency, a crayon will burn for 30 minutes. My question to you is this: What does a crayon define as an emergency? I have a box of 150, and would like to spread them out in the case they find such a situation that they spontaneously alight.
They will ignite when the planets align and the emergency makes its self present in the chaos of the universe unfolding onto us and folding in on itself as we weave in and out of entropy and enlightenment as the universe is explained as it is being destroyed. The crayons will ignite then.
