Then we'd become a bunch of skeptics who believe nothing! but usually I just take in the information that's given to me, if it's believable. I'm aware there's more than one way of viewing the situation but the other view isn't here, so we judge by the information we're given.
I do lots of shit for no reason...but I usually say that science is the reason.
I've nearly burned my house down for science once. I was trying to make fudge and it exploded. My parents didn't know whether to be pissed or impressed.
And on Tuesday I accidentally set part of my science experiment on fire. My lab partner and I had to work with a piece of foil with tape on it to see what would happen when heat was applied. We accidentally put too much heat and then FIREBALL.
I also nearly electrocuted myself when I was younger. For science.
