    Hmm. Both videos are working for me. Did you say something nice to your computer lately? They get cranky if you don't. :wink:

    Oh, sorry, I think it was my browser! Found it elsewhere.

    Is that a hint I should write something nice to davenn? Okay, awesome video Dave, very cool.

    Nope. Just a hint that you should give your computer tasty snacks everyone once in a while!

    I have to brag here: steak wrapped in bacon with fried mushrooms and onions with a stuffed baked potato. I think I've been nice enough today! :smile:

    I was thinking about trying that experiment by dropping my rent bill alongside some garbage down the garbage chute, but I don't think my landlord would like it.

    The first video is nice but there is a problem with showing it in slow motion only which is that those not familiar with the physics may get the impression that in a vacuum the acceleration of free fall is reduced.
