Hey guys- I’ve never been the most proficient when it comes to gadgets – I suck at rubik’s cube, and can barely program my dvr. I have a couple of these inflation adapters kicking around the studio, and I can’t figure out how to use them. Anybody want to help out a damsel in distress? If you do, please post instructions in the comments here. Thanks a bunch in advance!
