  - 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.

You've probably spun around a coin for fun at some point, but this physics toy uses the physics of a spinning coin to keep spinning faster and faster for up to 2 minutes. As seen on The Big Bang Theory, this physics toy, named after Leonhard Euler (pronounced "oiler") when spun on a nearly frictionless parabolic mirror will keep spinning faster as it approaches the surface until it finally comes to an abrupt stop.
