Camping purists may prefer to eschew traditional toilet paper in favour of nature's very own brand of sticks and leaves. For those of us who aren't quite ready to give up all the comforts of home, students have put together this clever, waterproof toilet paper dispenser to make outdoor defecating a delight.
The best part about the device, dubbed "Nature Calls", is that it's incredibly easy (and cheap) to make to yourself. Simply attach a zippered plastic bag to the top half of a two-litre bottle, and you've got a ready-to-use, reusable container to keep those delicate squares safe. Add a carabiner, and you can even hang this nifty little dispenser from a nearby tree — sorta kinda just like home. [Fast Co. Design]
