Half A Second
I’m trying to explain how close a 100m race is even though on the telly it looks likes there’s a distance between sprinters! There’s sometimes half a second between first and last. It's longer than a blink but....
So, how high off the ground would I have to hold a tin of baked beans (or any other readily available produce) in order to demonstrate how long half a second is between release and impact? Many thanks.

I saw that experiment too. I know… they must have filmed the sequence in a giant vacuum chamber. OR…they could have had the two objects connected to the ground by string and pulleys, Then when they were released a bloke pulled the string to bring them both to the ground at the same speed. OR…the feather could have been made of cast iron and painted white. OR…the ball could really have been a balloon. OR… (that’s enough.. Ed). :-)
