"My wife came back with this, and while I was initially impressed at the beautifully molded clear outer lid, and yes it achieves all the stated functionality, it leaves me wondering: why not go the extra step and include a vacuum pump? No not a clunky, expensive, complex electric one - a simple, hand-pump like the wine vacuum pump I use whenever I don't finish a bottle of wine. Furthermore, why can't I buy a valve like that which I can just drill into any of my plastic or metal containers that I want to be vacuum sealed?"

"So I have a kaweco sport fountain pen, and I'm really thrilled it has held up for 2 or 3 years now, rolling around in my pocket while I'm working, walking, on the playground with my kid, etc. I'm a bit disappointed the contact between the threads on the shaft and the inside of the cap is made of plastic - it doesn't fit securely, and I have to be careful to not turn it too much. Other than that, it's as solid as it looks."

"You want microplastics in everything you chop, every time you leave even the tiniest cut mark? Because this is how you infuse your gut with microplastics. Not to mention the credit card I thought I was saving the environment from by using it to scrape my cast iron - now I'm just grinding it up into toxic dust, instead of waiting for that to happen in a million years when a river runs through the dump. "

"Why is this any different from glass-fiber-reinforced parts? I get it that "fiberglass" is often unstructured, but it can be structured - for a few months, I worked for a tiny outfit making carbon fiber airplane parts by hand (back in Dallas in the early aughts), and we sometimes used glass fiber that looked just like those carbon fiber sheets, except clear/white. Even if non-directional, seems like all the resin-filling and forming steps would be the same as as a fiberglass/resin composite. What am I missing?"

"Saw way more badass looking tires for rolling on snow and ice on reddit and had to come back to share it https://www.reddit.com/r/funny/comments/lpv5ob/snow_tyre_naah/ - maybe somebody could find a 1 meter diameter rotary burr and put it on the back of a motorcycle, next?"

"Ok but what cheap utility wall-hooks did you find? Am I the only one who can't stand paying $14 to home depot for a piece of bent steel with a couple holes in it? Out on a farm is not the only place you want to hang a vast array of stuff on the wall - in fact I'd say the space constraints of city living make it equally compelling!"

"um how about a write-up of reverse-vending machines - that I only just heard of for the first time. And ideally their whole supply chain - do they also use the same trucks to bring stuff to/from the same factories? Where does the actual recycling happen?"

"Bookshelf with bungees would be pretty useful when you've got a 1.5-2 year old running around pulling everything off of shelves. I ended up wrapping several bookshelves with a single strand of monofilament for this reason. But the bungee thing is way too permanent for this usecase. "

"This maximal viable product sounds like an interesting concept, but I've gotta say if I were a resident of Redding, I think I'd be a lot less likely to give a designer a long leash after this experience. If you're aiming to expand the conversation about what design can and should be, I think it might be better to find examples that nail their objectives with core users, and maybe scoop up an extra usecase or two without breaking the bank. In this case, I'm thinking that both local dogs and taxpayers are a lot closer to the core users than sightseers who'll likely never visit again.  But hey even a design critique doesn't have to be a masterpiece on the first iteration - why not come back to us with an exploration of the important and real tension between making this park (and the city and region more generally) into a tourist destination, vs the need to have simple, functional infrastructure, and how that reflects and refracts thinking and designing like an engineer vs. like a starchitecht (e.g. see Frank Lloyd Wright's leaky and expensive to maintain buildings). "

"Amazing. Can't wait to see glass with a honeycomb structure interior, which will be much lighter. Then cover it with silicone stripes/dimples at strategic points to deal with breaking too easily, and you've got virtually a new material."

"So how does this compare to sunlight? My guess is that most viruses and bacteria are toast in direct sunlight for 10 minutes."

"Why wasn't this even mentioned on the front pages that I read religiously? Even Ars Technica didn't mention it. "
