How Ice Sculpting Works

Blocks of ice can be sculpted into anything from swans to full-size buildings. Find out how ice sculpting is done from HowStuffWorks.


Author's Note

I chose to go only briefly into the nature and behavior of sound because there are several HowStuffWorks articles that delve deeply into the subject. Perhaps best among these is How Hearing Works, which I mentioned in the section "Picking Up Sounds." The page on sound is also worth a look; and for those who really want to dig deep, check out How Virtual Surround Sound Works, The Sound of Silence and, one of my personal favorites, Can two cans and a string really be used to talk over a distance? (OK, that last one isn't that deep, but you know you've wondered.)
