Want to see what really happens while we're playing? Discovery Channel's "Time Warp" came to HQ about a month ago with their high speed cameras to film us in action and the results air on Wednesday, April 29 at 8:00 pm. It you haven't checked it out before, "Time Warp" is hosted by brainiac MIT scientist and teacher Jeff Lieberman along with digital-imaging expert Matt Kearney . . . they use new technologies to film all kinds of "ordinary" events and slow it way down so you can see the activity in a whole new light.

We had a blast hanging with Jeff and Matt, so check your local listings, and for more info, click here.
