it’s the mythbusters marathon on discovery and they managed to find a myth they couldn’t bust. it turns out that diving under water really will save you if you’re being shot at. the interesting bit was that older guns that fire bullets more slowly had a longer range under water than modern high speed weapons. in fact the faster the bullet, the less penetration it achieved under water. the whole time i was watching it i couldn’t help but think of the atriedes shield technology.
