Sometimes the simplest forms of technology are the most impressive. Case in point is a cool (very cool) science experiment from the Alaskan Alpine Club and various members.

What would you do if you lived in Alaska, had an abundance of water, a few industrial strength sprinkler-heads, and lots of free time? That's right, you'd build a gigantic ice tower. Starting from absolutely nothing (well, they had something, just not 152 vertical feet of ice), they slowly built the Ghost Raven Ice Tower over the course of about six months.

The simple explanation: Get a sprinkler running at full blast. Wait till the sprinkler's water freezes around it. Then use the existing frozen water (we'll call it "ice") as a base to extend the sprinkler system. Add more tubing, move the sprinkler higher, turn the water back on, wait for that water to freeze, then rinse and repeat.

Eventually, you get a science experiment that should be the envy of any mad scientist, a huge ice tower. And while the end result is amazing, it's also very interesting to see the process of its creation.
