We’re catching up with some of the footage we shot at BookExpo America last weekend (although editor Jason Boog has a pretty good head start!), and we thought we’d share this light-hearted moment from Sunday afternoon, when staff from the Chicago Review Press and University of Penn Press staved off boredom by launching candy over the wall separating their booths.

The catapult design comes from John Austin‘s Mini-Weapons of Mass Destruction, coming from the Chicago Review Press later this year.
