Yes. I really like the metallurgy version: An alloy can be denser than pure elements.
This raised a question for me that I have yet to research/answer. Maybe one of you knows... if the above solution is 50% ABV, what happens if I add one more part alcohol to the solution? Is it now 66.6% ABV? More? Less? How does ABV take into account the fact that this solution is packed together tighter than its constituent parts?
(To make the above solution 50% abv, btw, you need to keep adding water until it's 2 (liters, whatever) total volume.)
The muderation might be awful, but the users are sharp.
Learned something new, and I'm a chem grad.
