Boom

It was the annual INSPIRE Festival today - a day when students from local schools get to go to 'classes' on a variety of topics they wouldn't usually do and be inspired about their learning.  This year the classes' included learning about the brain and seeing and holding real brains, leaning some theatre sports skills and exploring why we study maths by looking at the engineering behind bridges.  So it seemed perfectly 'normal' to find the lunchtime 'entertainment' was blowing a small bin full of pingpong balls up.  Why?  Why not?!
