One of my biggest audiences of the year - 300 seat lecture theater packed to the rafters with new mechanical engineering students. I've only got half an hour to enthuse about the Library and its resources/facilities to them, but it's a great space to 'perform' in.

(The lecture hall where the delightful Ms Elena Bodnar dragged me up to demonstrate her bra that turns into a pair of facemasks in an emergency when the Ig Nobel gang came to visit.)
