There aren't too many things that breaking in half makes better -- but they are out there. After all, one can't make an omelet without breaking a few eggs. Taking this as a cue, perhaps it is beneficial to take a deeper look inside some familiar objects. While it is probably not a good idea to go around and start cutting everything in the kitchen in half, it seems a well-placed cut can help the lowly portable water bottle gain new life.
Easy to take for granted because they are such a part of regular life, reusable bottles blend into the background -- that is until someone cuts one in half. The Alex Bottle is a portable bottle that twists open from the middle as well as having a regular opening on top.
The Kickstarter has reached its funding goal is expected to begin shipping March 2015. It is still available internationally in a variety of mix and match colors for $34, which converts to about £22, AU$39, not including shipping.
Like many innovations, once they become reality, the implications become obvious. The first thing I thought of when I saw how easy the Alex bottle would be to clean was what else can I put in there? The answer is anything (even cracked eggs a la "Rocky" if one were so inclined). Since the opening in the middle allows for easy cleaning, there are no worries about unseen residue lurking in the darkness.
