  - Upcoming Unsifted Videos - active video submissions that neither are published to the front page nor archived to the submitter's personal queue
- Have you seen a really funny, surprising, scary, interesting, cute or in any other way extra good quality video?

  Mind you, we only share videos you discover that someone else has made; if you "self link," by posting a video you have made, have posted or have interests in, you risk the ban hammer - read the posting guidelines before posting. The sift is NOT for promoting your own videos - it is for sharing videos others have made.

I'd never heard it called a Galilean Cannon before, but I was doing this with two of my kid's balls this week. Kids love it, but adults are completely confused by how powerful it is.

Balance, say, a tennis ball on a basketball and drop them from chest height, and it will go so far that you will probably lose your tennis ball.

Do you own an exercise ball?

Yes, and I'm sure I had a baby around here somewhere.
