What keeps this car that's powered by an open flame from going off out of control and starting a fire?

Absolutely nothing! I just removed the drive belt/rubber band so that it doesn’t move

Where can i get the ethanol

You can use regular rubbing alcohol (isopropanol) but you can normally find "denatured alcohol" at many hardware stores, Walmart, AND on Amazon. Denatured alcohol is ethanol with a little methanol added to make it poisonous, therefore undrinkable. DO NOT use that HEET gas-line antifreeze stuff! That is 100% Methanol, and simply spilling it on your skin will get into your bloodstream and you may suffer from methanol poisoning (If it doesn't kill you, you will likely go blind). Use only SAFE fuels, like ethanol, isopropanol. (Maybe even lighter fluid will work?)
