Washing the Space Needle
A collection of photos of a cleaning crew washing Seattle's Space Needle with high pressure washers (scroll down a bit).
Even though the sprayers use half the flow of a garden hose, the water shoots out at 3,000 pounds per square inch -- more than enough power to send the guy behind the hose flying. "One thing we say is, it doesn't necessarily have to be fun to be fun. There are definitely times when I'm spinning in free space and I'm like, holy cow this is terrifying and I can't believe this is my job," said Matt Henry, rope technician.
The company doing the work, Karcher GmbH & Co., has done similar high-profile jobs around the world, all at no cost...their web site says that these projects are good publicity for their cleaning products. Here's a sampling of some other projects they've done, including the Statue of Liberty and Berlin's Brandenburg Gate. (via girlhacker)
