these are so fantastic I love the guy that throws up the jar? slips falls and the jar lands on him. right out of looney toons

Mine was the first one. I don't know how many times I've witnessed someone driving on the shoulder to beat a traffic jam just so they can get to where they are going sooner. Even after the traffic clears, that guy is going nowhere.

It's really quite simple, the physics/chemistry behind it.

Water is a polar molecule, the oxygen has a permanent partial negative charge on it and the hydrogen a permanent partial positive charge due to the significantly higher electronegativity of oxygen, which means the bonding electrons spend more time (are more likely to be found) around the oxygen.

When you apply a static charge to the balloon, the opposite poles of the nearest water molecules are attracted to it, causing them to orient themselves accordingly. Since that layer now has a uniform charge facing the bulk, the next layer of water molecules arrange themselves to maximize the attractive interaction there, and so on through the whole stream, ultimately pulling the water toward the balloon.

This graphic summarizes the point well.

If you tried the same experiment with a nonpolar liquid like hexane, the stream would be unperturbed.

my tap doesn't pour hexane, smart guy. :rollseyes:

Haha, I'm just saying, some of us have access to bottles of hexane and burettes with which to carry out such experiments whenever we choose...

What's interesting about that water video, to me anyway, is how it would change if it was solid H2O (ice).

The electrical properties of ice are so different from unfrozen water that it leads to a bunch of different physical reactions. For example if a flowing glacier were placed next to a proportional electrical charge (not really an actual chance that this happens), it's path would theoretically not be altered as much as the liquid water in the above video.

These may seem like nerdish musings but some of these "weird" properties of water are what makes life on earth possible.

I had always thought Puckhead was more interested in blondes.

Ice has a symmetric lattice, so the charge distribution averages out. Since the molecules are so rigidly packed in their configuration, the reorientation of the individual molecules' dipole moments wouldn't occur, and no, the glacier's path would not be affected.

Can you get your hands on some hydrofluoroether for me?

Yeah, um, what he said

Pretty neat optical illusion here. See how well your brain does "processing" this.

I haven't seen Django Unchained. Is this implying his wife was murdered so he stopped being a dentist and started rounding up criminals.
