Container conundrum

I have a drinking problem. I admit it.... and admitting it is half the problem, right? Oh, mine is not a problem of excess drinking, however. Mine is a quandry I think few others encounter.

Somehow liquids in containers with small openings seem to multiply. Let me explain. We have a very nice perk at my company. We have a virtual smorgasboard of drinkable liquids at our disposal. Our choices of FREE beverages include: at least 15 types of coffees (complete with creamer and your choices of sweeteners), 3 types of hot tea, orange juice, lemonade and no less than 8 variations of sodas. It is an embarrassment of riches. Luckily I am usually able to contain myself to 1 coffee in the morning, 1 tea in the afternoon and usually a soda with my lunch.

At the end of the day, I clean out the mug that I use for the coffee/tea, so 90% of the time I finish the hot beverages that I take from the kitchen. Sometimes they are even still hot! However.......about 90% of the time, I don't finish the soda and end up dumping 1/3 - 1/2 of a can out the next day. I hate that. I hate being wasteful.

Recently, for some reason, I started pouring the soda into a cup (I think it was because the top of the can was icky one day). The result? I drank all of the soda! Holy cow! It's a miracle! Since then I've noticed that if I empty the can into a cup, I drink it all. If I don't, I don't.

Is this odd? Is it a case of out of sight, out of mind? Have I discovered some sort of connection to an untapped diet coke reservoir at the bottom of my can?

The world may never know....well unless you chime in and let me know what you think the answer is!
