Set fire to your hair
Hair is highly flammable. Setting your hair on fire may result in heavy burns, or even death. Hair burns slowly, but if the burnee used hair products — such as alcohol-based hairsprays.
«Almost without fail, the organic solid residue of a hairspray is flammable (capable of burning with a flame). The fact that hair fires deal with solid hair and solid residue often leads to underestimating the flammability of the combination. One might think of the combination of hair plus hairspray residue as “combustible” because they are both solids. However no heat is needed to ignite the mixture. This is due to the high surface-to-volume ratio of the hair plus hairspray residue. An analogy is a lump of coal. As a lump, coal needs to be heated in order to burn. However, if the coal is converted to coal dust with a high surface-to-volume ratio, not only does coal not need to be heated in order to ignite, it is often explosive. <…> Because burning hair will often “drop down,” the person receives burns to the neck, shoulders and chest, sometimes to a greater degree than burns to the scalp. The individual’s clothing may also catch on fire exacerbating these types of neck, shoulder and chest burns.»
