Web watch - Josh Howgego investigates videos of enormous machines
I still remember the first time someone tried to convince me that a feather and a heavy metal weight would fall at the same speed if it wasn't for air resistance. But I clearly remember I was having none of it: 'No Mr Shoesmith,' I explained earnestly. 'The feather is lighter than the lead ball, you see.'
When I flicked through my browser to the Backstage Science website this week I had of course accepted the reality that a hammer and a feather dropped at the same time on the moon would fall at the same speed. But I had never actually seen proof with my own eyes.
