Troll physics is hilarious. The people who take it too seriously are pretty funny too.
Like djdupre I'm still figuring out why the string of air balls floating through the tank wouldn't work. I suppose there would be a lot of friction in the seal at the bottom of the tank.
The funny thing is I don't see why the air bubble one wouldn't work O.o
The best thing about troll science pages is the comments at the end
I'm pretty sure they actually used something like that bulletproof armour in Metal Gear Solid 2
I think the one about the telescope and mirror in space could be true, aside from little problems like building the mirror in space and the way our planet is constantly moving.
Successful physics troll is successful
You know how when you have to explain a joke it makes it not funny? It's the same with memes.
