  1. Awesome, that's exactly what I wanted to know. Thanks so much for doing the experiment
  2. Nice, thats kind of what I was looking for...just wish it was a cup (or a can ) instead...
  3. Arg! yes I did completely forget about horizontal montion...and I suspected the vacuum thing. How about if you jumped out with a sealed cup, turned it upside down, and then took off the lid ...
  4. Do you mean because its too difficult to not dump the liquid out while jumping out? I guess thats understandable. Otherwise, I don't see why not: The air resistance would be acting on the cup, not the liquid. So while the cup would be falling at the same speed as the diver (rate due to gravity minus air resistance) the drink would be "trying" to falling faster than the cup, effectivly staying inside. Things get interesting when you start tipping the cup to drink. Then the difference in pressure above and below the cup could cause wake regions or a vortex in the cup (like drag on an aircraft wing) and throw the drink out in a spray or randomly...I think... Maybe it would be possible to block the rushing air from below while by drinking while laying backwards? Or if you tried to pour the drink out below you, maybe it could it fly up (fall more slowly than you) into your mouth? It gets too complicated with so many possibilities...I just want to see someone give it a go
  5. I recently had a dissucsion with one of my friends about how one would go about drinking out of a cup while skydiving. As niether of us are skydivers (at least not yet...) and aren't too good at areo/fluid dynamics, we can't figure it out for ourselves. I've looked for ages but can't seem to find any reports, pics, or videos of someone giving it a try. Has anyone here tried it or know where I can find a video or something? Thanks
