Cool science

Bored with arguing politics. Something completely different.

That's cool - the BBC series with Brian are 2 of my favorites - Wonders of the Solar System and Wonders of the Universe.

Yeah they trick you. You think it's just cool, and the next thing you know, you learned something.

I have always known that theoretically that principle is true, and have been told in books that a feather and a bowling ball will fall at the same rate, but to see it for real was awesome.

They had something like that in the Boston museum of Science about 35 years ago. It was an exhibit. They had this tall plexiglass tube about 3 ft in diameter with all the air pumped out. They had these two hooks on chains like the kind you see in those arcade games where you try to grab the teddy bear or whatever. One of them would grab a pile of feathers and lift it to the top of the tube. The other would lift a ball of some kind, don't remember exactly. It would then drop them at the same time, and just keep repeating this automatically. It's much cooler to see it full speed. What's with the slo-mo?
