In this question we are comparing an electric lighter, an electric lighter versus a putane lighter.
00:12
And what is important to note up front is that the putane lighter is more efficient.
00:18
So when we look at the putine lighter, the properties of these two lighters, the flames of these two lighters, they are quite different.
00:27
So for example, if we are to look at putane, when we are looking at putine, butane emits a blue flame.
00:37
We've got a blue flame.
00:41
And this is because there is complete combustion, complete combustion, because it burns in the presence of sufficient amount of oxygen.
00:54
So what facilitates this complete combustion is presence of excess oxygen.
01:02
Not necessarily excess, but a sufficient amount of oxygen...
