I have a 74 oz plastic water bottle that I really love, (It has a handle, and is perfect for when I'm working out). The problem is that when I drink, it makes ALOT of noise, when the bottle is filling with air instead of water. I just had another bottle that was almost identical, but was made out of a slightly different material. It broke, so I threw it out, but it didn't ever make this noise. What's up with this, anyway? I'd really like to fix this, so that I can use it at work.
