This was a candidate for YouTube video of the week tomorrow, but it was so awesome that I just had to post it today. A man’s built a TREBUCHET and it throws FIREBALLS. Oh, and it’s called “Mongo”. That’s all you really need to know. Skip to 2:55 for the best bit. Have you built a siege weapon in your back garden? Take some photos and send them to us, and leave a comment below.
