Was feasting on my Pret sandwich during lunch the other day as I was strolling beside the Tower of London. when I saw the live demonstration of a trebuchet, more popularly known as the catapult. Though I'm sure the two devices here are very different but let's not go into the technicalities here, shall we?
Anyway, they got burly men dressed up as medieval soldiers who entertained some tourists in what used to be the moat of the Tower, which has since been drained. Those soldiers looked pretty bored and by the look of their faces, they could have been standing behind the fish n chips' counter.
Apparently, the device was supposed to send a projectile across the length of the moat and hit a target (not in picture), which was easily 50m away.
I spent my entire lunchtime watching the process and when I left 45min later, the two bored looking soldiers were still explaining the mechanism to the dwindling crowd. Darn, should have walked across the Tower Bridge...
