Dress a teacher or a kid up in armour. Talk a little bit about different types of armour. Avoid all topics of politics and religion.
And we even get a chance to hold a real battle sword. With me holding the other end, you bet!
I bring a large quantity of pliers and rings, and the kids try their hand at making chain mail. Surprisingly enough, their attention stays focused.
Of course, there is always lots of other armour around for them to try on! Mostly chain mail, but a some other armour. Most is too heavy of course.
This exhausting job is made worthwhile by big grins on people's faces!
