Abingdon bun throwing

Sadly we were unable to be there but friends who were said it was great. Here's the video of this weird old ceremony http://www.oxfordmail.co.uk/news/14551727.VIDEO__Cloudy_with_a_chance_of___buns__Crowds_in_Abingdon_covered_with_bread_for_Queen_s_Birthday_ceremony/?ref=arc Buns are thrown from the top of the old building onto the crowds below. I tried timing the fall. The motion is parabolic. Vertical fall is independent of horizontal movement. I think a time of about 2 seconds is quite close. Timing from individual hand on the roof to hitting the ground is difficult. The equation needed is height = 1/2 x g x time-squared = 1/2 x 10 x 4 = 20 metres. Not too bad.
