The Primus Stove

To light a Primus, you first prime the cup with meths, which must burn to completion. Then you pump the plunger like mad and hope the meths provided enough heat to evaporate the avtur (paraffin) main fuel. Get it right and a welcoming blue flame roars. Get it wrong and a sooty fireball fills the tent!
