Trebuchetting at St Virgils

I was asked to provide a trebuchet demonstration at St Virgil's Grade 8 Medieval Day.  I took the little one & the scale model.  The school  provided a small section of castle wall as a target.  4 groups of boys had a great time hurling a mix of fruit, water bombs & bocce balls at the target at a range of 50m (the machine's max range is about 100m, but I kept it powered down for safety reasons).  Every group managed at least a couple of hits, including some through the window or castelations to take out the defending bowmen.  The hits on the MDF wall went straight through.
