Make Fire from Sulphuric Acid and Potassium Chlorate

Disaster! You find yourself lost in the wilderness, night is approaching and you will freeze to death if you don't start a fire quick! You are not carrying matches, flint or lighters.  Luckily you happen to have sugar, potassium chlorate and concentrated sulphuric acid on your person.  Phew.

Prepare yourself a bundle of twigs and hay and in the middle, add a pile of 50/50 mixed sugar and potassium chlorate.  Slowly add drops of sulphuric acid until it bursts into flames.  Safe at last!

Remember kids, always carry concentrated sulphuric acid, sugar and potassium chlorate with you at all times.  

Here's how it works: 

Sulphuric acid reacts with the potassium chlorate to form potassium sulphate, hydrochloric acid and a lot of heat...
  • 2KClO3 + H2SO4 →  HClO3 + K2SO4
The heat decomposes the potassium chlorate into oxygen...
  • 2KClO3 => 2KCl + 3O2
The large oxygen supply plus the high temperatures causes the sugar to burn violently.
