This photo is actually misleading. It's filled with water - not Coke. But it is a nearly empty Coke bottle. This photo is more to prove to you that these photos ARE taken day by day. Look in the background for proof of this.
It will not be long before I begin to make these photos more and more vague as time passes. needless to say, it'll become a puzzle at some point. :D This first 5 days are merely a warmup. Hehe.
