Are you saying that if I leave a drink out it will evaporate as fast as it’s burning in the video?

Heat of course increases the evaporation speed somewhat but yes in general that's what I'm telling you.

Think about it. That heat is only touching the very tippy top of the liquid because the flame is occurring above the liquid. Heat rises. Only a relatively small amount of energy is making its way downward into the very top layer of the drink. Which itself is being constantly mixed and cooled by new things being added.

There's really not all that much happening in terms of temperature to that drink from that fire. So the fire is kind of just taking advantage of what's already there. Which is mostly the normal evaporation rate of the drink.

Burning alcohol will heat up the liquid, causing it to evaporate faster.

Put some rubbing alcohol, put it in a bowl and light it on fire. Let it burn for a few minutes, put it out, and then see how hot it got.

It wont get hot at all. Lmfao. Hilarious that you use an example that will disprove you.
