Default Re: vented vs. non-vented....

Put a straw into a glass of soda. Place a finger tip over the exposed end of the straw. (No vent) Lift the straw and notice how the soda does not exit the straw but rises above the fluid level. Take your finger off the straw and the fluid drops back down into the glass. (Vented)
