I have never cared for plastic 16 ounce soda bottles.(Especially Coca Cola) I've always found them to be unstable and fall over easily.

I now despise the things, as they are nigh impossible to open with only one working hand. I've been able to open most bottles and jars by clamping them between my right arm and body and removing the lid with my left hand. This method doesn't work with soda bottles as the plastic is so flimsy the bottle immediately crushes once the pressure is released and before the lid breaks free from its ring. This results in copious amounts of sticky soda being sprayed about the area as well as one very annoyed and still thirsty tiger.
