Prove it.

Physics is on my side.
I don't know why people find it hard to face facts.
I'm guessing you aren't very advanced in your physics learnings? I'm also guessing the second guy doesn't understand the meaning of the word 'fact'.

Well with one quick search this is what I got on wikipedia.

Even though THC and other cannabinoids are alcohol-soluble, such a small area of the smoke (i.e. the surface of the bubbles) comes into contact with the bong water that it is negligible.
Therefore, the reasoning is that while THC is absorbed in the alcohol, it is only a small amount because of the small surface area of the bubble and the majority of the THC is inside the bubble. Minimal amounts of THC are still lost though, so looks like your gr 2 physics has been debunked.

I'll go get more studies.
