We can use hand sanitizer until the skin on our palms dissolves and falls off - the world will still be full of nasty germs. But this CleanWave Portable Sanitizing Wand ($40) uses UV-C light to kill viruses, bacteria, and even some fungi. With it, we can give in to our OCD tendencies and wage war against microscopic enemies at home, work, and abroad. Heck, it might even mean we can stop hovering when we're using public restrooms. Not that doing so isn't a great thigh workout.
