To the point of being trampled by a vehicle 
The main principle is a mixture of two chemicals:
Phenyloxalate esters and hydrogen peroxide
They react together to form a fluorescent substance.
Cyalume has designed a packaging that consists of a plastic stick.
2 pieces contain 2 types of chemicals together. When we break the inner capsule
The first chemical container is mixed with the second one, causing a reaction.
