Bears are unlikely to be a problem where I am but might be a problem elsewhere. However, yes, squirrels would be a bigger problem. That's why the flexible barrier exists. I don't like the idea of tongs, as they might disappear. It also seems needlessly complex.
By the way, KISS is at the center of this. The overly complex, overly secure boxes you see can be difficult to use and who needs to have a lock on their doggy bags?
LOL! I don't think the bears would be good partners.
Seriously, though, anorlunda is right. As a cost control measure, and to increase the invested feeling of the frequent users, used plastic grocery bags, bags used to wrap or enclose shipped materials, or even small garbage bags or ziplock...
I don't get the math, unfortunately, but your BOLD statement seems to be the equivalent of saying the obvious. If A is equal to B then we have equilibrium and the boundary is the equal sign between them. Of course I may be oversimplifying it. But you may also be overcomplicating it.
Just a thought.
I can (and intend to) use that as part of the dispensing system. However, unless your bag dispensers are different from the ones at my grocery store, they have little protection from the elements. Being open also means that the bags tend to come out in random bunches if we are using formerly...
My name is Lois, and I am a 70-year-old grandmother who is reasonably intelligent and occasionally finds a problem which should have a solution, but the solutions presented are just not good enough. For instance, when I started looking for a better solution to dispensing bags for disposal of dog...
Rather mundane, I'm afraid. I want to make a bag dispenser system for beaches and trailheads that will dispense previously used plastic bags (like shopping bags, and everyone has at least a bag full of bags) one at a time and will allow for a human hand to easily enter and get out one bag...
Visualize a lid to a toddler snack cup. Making an entry into an object which is to be placed in nature which can be used by humans but not easily by animals, would the curves used in some toddler snack cups be more durable and flexible without being floppy, or would straight line radii from the...
