We're constantly being told to drink lots of fluids, but buying fresh bottled water is expensive and a waste of resources, and while reusable drink-flasks (or old plastic bottles) can be refilled, they take up space when not in use. The Bübi Bottle offers a simple-yet-elegant solution to the problem - it's scrunchable.

The energy used in manufacturing bottles is vast. Most then end up in trash cans rather than being recycled, adding more waste to the process. There are an estimated 200 billion bottles of water sold around the world annually and every little bit helps when it comes to putting a lid on this recent and unsustainable trend. That's why reusable water bottles are a good idea.

There are already reusable bottles on the market which can be rolled up when not being used (such as the Vapur) but they generally lack rigidity owing to the material they're manufactured out of. This can make drinking from one feel like you're sucking on a carrier bag - a pastime I personally try to avoid. The solution, as inventor of the Bübi Bottle Craig Madaus saw it, was to change the material of the bottle.

The Bübi Bottle is made out of high-grade, BPA-free silicone, making it great for holding any drink you care to pour into it. The insulating properties of silicone means it will keep hot drinks hot and cold drinks cold, at least for a period of time. It's also flexibile, meaning the strong-yet-supple Bübi Bottle comes into its own when not in use. It can be scrunched down to a fraction of its original size - with a ring keeping the body rolled up neatly - and placed in a bag until it's ready to be refilled.

The bottle measures 9.5 x 2.75 inches (24 x 7 cm), holds 22 oz and is dishwasher, freezer and microwave safe (you need to remove the carabiner for the microwave).

The Bübi Bottle is available in nine colors and at US$29.99 it's far from the cheapest option available - but it is scrunchable.
