Soda rots your teeth. Straws prevent this a bit but sucking in all that air over and over makes you gassy.

What about a straw with a simple one-way valve so that the fluid stays near the top of the straw?

you would still have to suck, plus no one would buy them b/c they would be about 50 times more expensive. anyway i like burping, i can't at resturants, but everywhere else i go crazy, lol. and you can stop the soda in there by plugging the top with your toung or finger. it's inpractical, but then again... so is this idea. if this is the biggest problem in your life, i wanna trade, lol.
