Because it's Friday, and because some things are funny even when you're a grownup and you know you they shouldn't be funny anymore, here is a treat from NASA: A training video for the "space potty" that astronauts use aboard the space shuttle Atlantis. You'll never think about "alignment" and "docking" the same way. (Atlantis, incidentally, just blasted off on what will likely be its last mission. But that's another story.)

If you like Mike Massimino in this video--he's the one who isn't fidgeting uncomfortably--check him out in NOVA's Hubble's Amazing Rescue and NOVA scienceNOW's Saving Hubble

Wow. What a Friday night treat! Now I know how to answer one of the top ten questions every schoolkid asks--and parents wonder about as well. "Alignment is your friend." Indeed. Thanks, Kate!
