I always assumed the kids (here we've got Luke, Silas, and their friend Garrett) were drawn to the post-petting-zoo hand-dryer because it was their height and controllable by them. But looking at this photo a little closer revealed a couple of interesting things:
1. The fun fish-eye reflection may be the real draw!
2. Northside Hospital sponsored the device?
