What the Heck Is This?

If you've never seen this image before, it'd be hard to guess exactly what it is. But you might have guessed parts of it. Three hints:

It's a water bubble with candy trapped inside, floating freely on Endeavour. The photo was taken March 14, 2008. Astronaut Dominic Gorie, mission commander, holds a string near the bubble (see the full version below).

Check out also below a widely seen image of space shuttle Commander Loren J. Shriver pursuing floating chocolate-covered peanut M&M's on the aft flight deck of the shuttle Atlantis, with Earth in the background. It's an iconic image that reminds us how much fun it would be to go up there.
