Standing on hands...lose weight?

The difference is they weren't testing the weight of the truck + the weight of the birds, then having the birds fly around and see if that made the weight of that closed system lighter. What they were testing was the weight of the truck itself and having the birds fly around and see if that made the truck itself lighter.

OK. But really that is the same thing. Your baseline is just different.

The only reason why it appears to be the same thing is because the birds' weight is fairly negligible, being they weighed a couple of ounces. If the birds weighed 50-100 lbs, then it wouldn't be the same thing.

Take a look at isukendall's post. What I would like to know is that if the 2 buckets were connected by a tube, would you see the same weight change when you pour the water from the top bucket to the bottom bucket.

You change change your mass without "giving up" something. Standing on your hands would do nothing. Assume your body to be a control volume. If nothing leaves it, your mass hasn't changed. More likely, it was an inaccuracy of the scale.

If you're in an elevator and the cable snaps, will jumping up at the last second save your life?

Umm what? How does that change what you weigh? The best bet is to pee pee pee and pee, do anything you can to get as much waste out of your body as possible.

when you haven't drank more then 8 oz. of fluid for 2 straight days and have lost an average of 8 lbs a day in those 2 days, you really don't have much left to pee out or dooty. your best bet at this stage is to go outside and use the old finger down the throat trick. this usually works to get rid of the last couple pounds. if you start coughing up blood, you may want to consider moving up a weight class.
