"When nature calls" – it's something we all have to respond to, and it can make outdoors adventures a tricky prospect for those used to life's little luxuries such as quilted toilet paper and something more than a hole in the ground. When Nature Calls (the proposed product, not the saying) solves the first issue, though there's little anyone can do about the second.
When Nature Calls is the work of Amy Pon, Sarah Jensen, Janet Molchanko, and Morgan Smith, all students at the Alberta College of Art & Design. They were tasked with creating something that "generates social or economic value" using a 2-liter soda bottle. The result of their brainstorming and design sessions is a simple storage device for toilet paper.
The soda bottle becomes a toilet paper dispenser, with the addition of a resealable bag keeping the whole thing waterproof. The hypothetical product is completed with "reflective tape, silicone, twine, and recycled paper." With a few additional items it can be hung in a handy place and have a light attached so that night-time toilet visits are made more tolerable.
If When Nature Calls ever becomes an actual product the students plan to donate the profits to the Canadian Parks and Wilderness Society. However, as all of the materials used are reclaimed there's nothing to stop anyone else making their own version for free... though I'm sure the CPAWS would appreciate a donation all the same.
The plastic bag has a hole in it to let the tp out. I surmise that is sealed with the cap of the bottle when not in use. However there is going to be a gap between the edge of the bottle and the bag at the top. Water WILL get in there, as it gets everywhere. There is no place for that water to go. So now you are faced with drying the unit out before you ever replace your tp, and or having a pool of water when you need to take the cap off the bottom.
Would be better to reuse the bottom of said plastic jug somehow.
Also im pretty sure the bag is sealed to the bottle, so no water getting in. It doesn't say exactly how its made so we can't be sure, but it looks like the bag is under the brown label.
I don't think this thing has tremendous amount of value, but it has some value and seeing the simple materials its made from, some being recycled, i think its a good idea and a good effort at trying to make something useful out of a 2-litre bottle.
I just dont see it being much better then putting a TP roll in a ziplock bag.
