China builds a jet-propelled water cannon, just because it can (video)
Just what does $456,000 buy you these days? Well, if you happen to run the fire department of China's Luoyang City, the answer is a jet-propelled water cannon capable of spraying four tons of water per minute. That pretty much qualifies it for a "terminal velocity" badge, as the water is said to move at such speed as to choke fires from the oxygen surrounding them. Maximum range for this blaze blaster is 120 meters (nearly 400 feet), though you'll need to only move a fraction of that distance to click past the break and watch the awesome video of it in action.
