Once a week we’ll send out a page from Cool Tools: A Catalog of Possibilities. The tools might be outdated or obsolete, but the possibilities they inspire are new. Sign up here to get Tools for Possibilities a week early in your inbox.
I carry a roll of the Velcro Plant Ties (see right) in my tool bag, but also keep One-Wrap Velcro strips in the shop. While they’re much more expensive, I’ve found the larger kind to be substantially bulkier and stronger. Here in Toronto, we have alternating weekly garbage, recycling, and green waste pickup. We also have rapacious raccoons. I found if I add a simple loop of One-Wrap, screw it into the side of the green bin and loop it over the locking bail of the bin, the raccoons cannot open it. I first tried Plant Ties. They just wouldn’t hold. For my purposes, a One-Wrap is good for about a year, after which it is easily replaced. It’s available in various colors and sizes. The lower-end of the One-Wrap line is a similar size to the Plant Ties, which are 13 mm wide; however, the One-Wrap also come as large as 22mm. It has deeper loop Velcro (thicker and fuzzier), and as the width of the tape increases, the size of the loops and their grip strength increases. Plant Ties really are great for handling all kinds of tasks, but One-Wrap is strong enough to bundle thicker rope, heavier hoses, and most importantly for me, they keep raccoons out of the recycling. – David Keldsen
To me, as a commuter, one of the most impressive parts of the EZ Pass toll-paying system is the hardcore industrial “velcro” tape they give you to attach your transponder to your windshield. It’s not really velcro, though – instead of hooks and loops, both surfaces have these tiny hard plastic mushroom-shaped things that grab each other by the hundreds and don’t let go. Both sides are the same, so there is only one tape (called selfmating). And unlike the loosy-fabricky velcro connection, the Dual Lock surfaces don’t join until you’ve positioned them exactly, and then pressed them together with a satisfying “chunk.” They’re primarily used in industrial applications as a replacement for mechanical fasteners, but I use mine to attach my iPod to my dashboard, and tools to the wall in my workshop. – S.S.

Parachute cord isn’t only light and strong (550lb. rating) for its size (5/32” diameter), it’s also more versatile than other types of rope because it can be dissected and parted out, cut and used for its braided nylon sleeve and/or seven separate core strands.
You can get an enhanced grip and a little added padding by using paracord to wrap tool handles. It’s also used for making lanyards. I recently inserted a length of ball chain into a parachute cord sleeve to make a hands-free flashlight for late-night dog walks. The nylon is a lot more comfortable around my neck than a ball chain, and the fit is perfect. – Spencer Starr

Cool tools really work.
A cool tool can be any book, gadget, software, video, map, hardware, material, or website that is tried and true. All reviews on this site are written by readers who have actually used the tool and others like it. Items can be either old or new as long as they are wonderful. We post things we like and ignore the rest. Suggestions for tools much better than what is recommended here are always wanted.
Imagine a patient in a vegetative state who can actually feel everything happening to them but can't communicate it. Picture an octopus being boiled alive, experiencing every second of agony. Consider an AI system that might be developing genuine feelings while we treat it as just another tool. These are the ethical questions that keep Jonathan Birch up at night.
As a philosopher and ethicist at the London School of Economics, Birch has spent years grappling with one of science's most perplexing questions: how do we know if another being is conscious and capable of suffering? His book, The Edge of Sentience, argues that we've been asking the wrong question all along. Instead of demanding absolute proof of consciousness — which may be impossible to obtain — we should focus on identifying "sentience candidates" and taking practical steps to protect them from harm.
This isn't just academic theory. Birch's work has already influenced real-world policy — he led the team whose research convinced the UK government to legally recognize lobsters and octopuses as sentient beings. Now he's turning his attention to an even broader range of cases, from human patients with brain injuries to the possibility of conscious AI.
Here are four key insights from the book:
"Assume Sentient" When Lives Are at Stake
"A patient [with a prolonged disorder of consciousness] should not be assumed incapable of experience when an important clinical decision is made. All clinical decisions should consider the patient's best interests as comprehensively as possible, working on the precautionary assumption that there is a realistic possibility of valenced experience and a continuing interest in avoiding suffering and in achieving a state of well-being, but without taking this assumption to have implications regarding prognosis."
Look Beyond Brain Size and Intelligence
“Sentience is neither intelligence nor brain size. We should be aware of the possibility of decouplings between intelligence, brain size, and sentience in the animal kingdom. Precautions to safeguard animal welfare should be driven by markers of sentience, not by markers of intelligence or by brain size.”
On the Hidden Nature of Experience
“At least in principle, there can be phenomenal consciousness without valence: experiences that feel like something but feel neither bad nor good. It is not clear that humans can have such experiences (our overall conscious state arguably always contains an element of mood). But we can conceive of a being that has a subjective point of view on the world in which non-valenced states feature (it consciously experiences shapes, colours, sounds, odours, etc.) but in which everything is evaluatively neutral. Such a being would be technically non-sentient according to the definition we have been using, though it would be sentient in a broader sense. Would such a being have the same moral standing as a being with valenced experiences?”
On Future AI Risk
"As these models get larger and larger, we have no sense of the upper limit on the sophistication of the algorithms they could implicitly learn... The point at which this judgement shifts from correct to dangerously incorrect will be very hard for us to see. There is a real risk that we will continue to regard these systems as our tools and playthings long after they become sentient."
