The point of this exercise is to find out how the lighter works, not to light something...

At a guess I'd say a pizo-electric crystal (probably based on the perovskite structure) with a cunning lever system to maximise the pressure applied. Pressing the lighter button causes pressure on the crystal producing an electric dipole which is used to cause a spark and ignites the gas.

Just a guess though.
They might use a battery.

The spelling in the above comment is 100% correct. It's the rest of the world that got it wrong.

That's pretty much it. I think they use a hammer of some kind, though.
