SUMMARY
The discussion explains that when using two straws to drink from a can, both straws must be submerged to create an effective vacuum. If one straw is out of the drink, it causes air leakage, which reduces the negative pressure in the mouth and requires more effort to draw liquid through the submerged straw. The mechanics of drinking through a straw involve reducing pressure above the liquid, allowing atmospheric pressure to push the liquid up. This principle is similar to the operation of pressurized spray cans, where higher internal pressure forces contents out when the valve is opened.
