I'm as game as the next guy for making fun of those travelers who load up on hand sanitizer for a trip, as if there are somehow 10 times more germs abroad than at home. (The germophobe gets a starring role in the new Nim's Island movie, with an ongoing Purell product placement via Jodie Foster.)
As a parent though, I know there are times when your kid is carrying a whole petri dish of stuff on his/her hands. But then it's time to eat the airplane or food stall snack, with no sink and soap in sight.
This cool little hand sanitizing spray device from CVS lets you kill all the germs without loading up your bag or worrying about the 3-ounce carry on rules. It's the size of a large ink pen and has all of 0.17 ounces (5ml) in it. The protective top even has a clip for hooking it to a pocket. Pull the top off and there's a little spray nozzle. No mess before or after.
This mini hand sanitizing spray fits into a purse or pocket easily so you can keep it handy in flight or while on the move. It retails for a mere $1.79 at their stores, so this is one gadget impulse buy that you won't regret later.
