You can never have enough free hands at the airport for juggling your boarding pass, your passport, your coffee, your snacks and your carry-on bag. The solution to that problem came to amateur inventor Robert Lian while he was waiting for a flight one day. What about a plastic tail that let travellers tow their luggage like a trailer? The only real requirement for the My Hitch, besides being cool about walking around a crowded airport wearing a fake plastic tail that's dragging your suitcase, is you'll need to be wearing a well-secured pair of pants, preferably with a belt keeping them tight around your waist. Try to use the My Hitch with something like track pants and they will end up around your ankles in no time.
Carry-on bags weighing less than 11kg are considered ideal for tail-towing, and you'll want to avoid stacking luggage which could throw off the balance. Otherwise, for just $US18 ($24) the My Hitch leaves your hands free for other important tasks like trying to hide your face while everyone else is trying to take pictures of you walking through the airport.
