KwikTop locks down your beverages

If you're sick and tired of your roommates or coworkers guzzling all the soda from the communal fridge, there's a less extreme (though, perhaps, less satisfying) solution than refilling the beverage bottles with the sludge from the bottom of the soap dish. It's the KwikTop, a combination lock that slips over the top of a soft-drink bottle. The manufacturer also sees a market in spots like gyms, bars, or other locations where someone might inadvertently lock lips with your drink. We could definitely use one in the corner coffee bar where we park our laptop every morning — we have a sneaking suspicion that every time we take a bio break,
someone's messing with that bev we've left behind, and we're ready to fight back.
