We all unfortunately know backwash: the floating chunks of mystery meat you see in your buddy's drink from time to time. There's a simple solution to backwash: a mesh sieve, with slits just large enough to let water into your mouth but small enough to keep your half-eaten custard cake out of your drink. Like a strainer for your soda. It just pops on to the top of any standard sized pop bottle, easily removed and simply cleaned with water and a shirt sleeve. Simplicity does it again.

Didn't your mother tell you not to drink out of the bottle?

The point is this: what's worse: saliva in your drink or saliva and whatever they've been eating in your drink.

Also, saliva, if I'm not mistaken, has a higher viscosity than water. Meaning that if the holes are small enough, the saliva will 'float' at the top of the sieve without contaminating yur drink.

Better to drink from those beverage squirt bags popular amongst Spanish wine drinkers.
