Ever been to the gym with an empty water bottle, only to find that you had to twist it, and tilt it and nearly break it in order to get it filled at the water fountain? And even then, you probably only managed to get it half full. Well, that could all change if 15-year-old Anna Axelsson’s invention takes off commercially. She created the Binibottle, which features a sunken twist cap on the side (in addition to the twist cap of the top of the bottle). This allows you to refill it in a horizontal position. This simple addition was so innovative, that it earned her a gold medal in a Swedish invention contest.

Currently, the Binibottle is available in Swedish sporting goods stores for about $5, but here’s hoping we start seeing it elsewhere.
