An Indy car ignites in an alcohol fire, which is completely invisible!

Are we sure this isn't a very elaborate Monty Python sketch?


While I am sure this is a joke, you can actually do this experiment at home with alcohol. Get yourself some everclear or some other very highly pure ethanol and set it ablaze. And did you notice he used the word inflammable. That is the correct word, we only recently made the word flammable up because it confused to many people.

At the time of this videos, Indycars ran on methanol rather than ethanol. Ethanol has a very faint blue flame, but methanol is almost perfectly clear, though you can see the flames as sort of a shimmering disturbance in the air. These days Indycars run on ethanol, but it's more of a marketing thing than for any practical reason... the racing industry is hard up to show how "green" they are.

The main reason these kinds of fuels were phased out of sports.

They still used alcohol fuel, which is a mixture of ethanol with 2% gasoline to make it burn visibly.


Yes, I didn't want to imply alcohol was removed, just the invisible ones

Wait... so let me see if I get it... the fire is invisible and cannot be seen? Ahhhh, I think I understand now.


No, you've completed misunderstood. Think of a fire, right? But imagine one in which the flames are not only completely invisible, but also cannot be seen. Its still a fire, it burns hot, you can feel it's heat, right? But you can't see where it is and no-one around you can see it either. The human eye is simply incapable of detecting it. So if someone was on fire they would feel it burning, but they couldn't see it, you couldn't see it and no-one else could see it. So now imagine it's you on fire and you've got to explain all that to someone else in order to get them to understand that although they can't see the flames, because they're invisible to the naked eye, that they still need to put out the flames to stop them burning you.

If only there were some kind of easily recognisable signal you could give in such a situation.
