Sadly not beer
We used to issue bootcamped MacBooks to our PhD students - it was a solution to not enough space for desks, but inevitably, I needed to repair them.
One day, I found one on my desk to fix, and I thought I could smell something. When I got the thing open, it stank like the broth of hell - fairly appropriate analogy the student had managed to spill fish soup on it and waited a week to bring it in.
I actually tried to rescue it, sponging it with de-ionised water, but it was beyond redemption.
At least the next one had only been bathed in baby oil.
I never plucked up the courage to ask the student how that happened.
