One hectare is about the size of a soccer field. Source: Prof. Mike Flannigan, Univ. of Alberta   COLOUR MY FLAME The colour of the flame depends on the mix of fuel and oxygen. At the bottom of a flame, there’s more oxygen, which “excites” the molecules causing them to glow blue. Higher in the flame there is more soot (carbon particles), which glows yellow/orange.

Heat makes the air expand and take up more space inside the marshmallow, forcing the gelatin mix to stretch. Yum.

One theory suggests he could have encountered Dictamnus albus, a desert shrub known as the “gas plant”. In the heat of the summer, it creates a methane-like flammable substance that can ignite spontaneously.  Source: http://nowiknow.com/burning-bush/   THAT SHAKESPEARE WAS LIT! In 1613, London’s Globe Theatre was accidentally set ablaze when a cannon misfired during a performance of Henry VIII.
