Years ago a couple of my (ex)friends were up all night drinking waaaay too much and they put a tiny goldfish in vodka. I wasn't there to witness, but they said the poor thing was trying to process the fluid and ended up bleeding out of its gills. I was worried that was going to happen here and that was something I really didn't want to see. This sort of turned my stomach.
I honestly don't think there was anything "cool" about that video. It took me a while to actually click on it, and I expected it to not be what it looked like when I did...
BTW, It has been clinically proven that people who torture animals tend to have latent psychotic issues. Ha ha, a goldfish being put through excrutiating pain. 10 years down the road your in jail because you beat your toddler to death for spilling milk on the carpet.
