but they didn't show them landing at real speed ONCE!!!
Edit: to be clear, they both fell at about the same speed the bowling ball would have normally fallen (bowling balls have low air resistance).
In this cheesy science video, they make it clear that the bowling ball and the feathers land at the same time. but they don't make it clear that they're both falling pretty darn fast.
the amazing thing would have been to see the feathers falling at about the same speed as what a bowling ball normally falls. that HAPPENED. they just didn't show it.
