Now that the warm weather is here, you’ll likely have lots of get-togethers with friends and family to share laughs, food, and germs. Ah, lovely germs. That communal chip dip bowl might be growing something funky other than that blue cheese Aunt Sally threw in.

While I don’t mind sharing the occasional drink or snack with someone I know and like, there are always a few double-dippers at every party who end up essentially sharing their spit with everyone at the party (well everyone who uses the dip, that is).
