Mars bar
"It's not so much the energy it contains as the method you use to get it out."
Er, no, it's not like that at all.
A Mars bar on its own "contains" no energy. You need an oxidiser, because the energy comes from the redox reaction of carbohydrate/fat with oxygen.
Now, if a Mars Bar consisted of the usual ingredients finely mixed with a suitable quantity of potassium perchlorate, you'd have something they wouldn't let you take on aeroplanes. Before they got hold of Semtex the IRA were rather keen on chlorate/sugar as a method of bringing Marxism to Ulster.
