...Bushway, a science teacher at Barrie Middle and Upper School, wondered aloud to her upper-level high school chemistry class if there was a little filter — similar to the ones that are made for camping to purify water — that they could make from inexpensive components to easily remove lead. The students were excited about the idea, and they started thinking about the project in 2020 when COVID-19 restrictions kept them out of the classroom. While at home, the team met virtually and discussed designs for an attachment to screw a filter onto a sink’s faucet. Then in the spring semester of 2021, when they returned to the classroom, they 3D printed the attachment and a 3-inch-tall filter housing, using a biodegradable plastic. Their final step was to fill the cartridges with a mixture of calcium phosphate and potassium iodide powder....
...And while the chemistry itself is pretty straightforward, crafting the water filtration system to do what the researchers intended has been more complicated. For instance, calcium phosphate tends to clump up, causing the reaction rate between it and lead to go down as the surface area decreases. So, the team’s lead student engineer incorporated hexagonal bevels inside the filter....

maybe upsize it for water main connects before it ever gets into the home?
Just make it for the screw in cartridge size filter blocks.
Don’t existing faucet filters already remove lead?🤔
Cool, we can start using lead pipes again!
Cheap and easy to work with.
Where was ClockBoy on this?
Yeah - but this one was made by high school students. So that makes it better.
/sarcasm
I don’t know...
Those kids sound kind of white to me...
Ping. I’m gonna keep an eye on this. I could use one, or two, or several!
They might be able to make them at a cost of $1 each, but after you add in packaging, shipping, warehousing and distribution, retailing, marketing, and general and administrative expenses, they will have to retail for upwards of $10 each.
It’s not cheap to get stuff from Southeast Asia to the American consumer.
Cool, we can start using lead pipes again!
- = - = -
It’s a cinch!
Great, now do that other neurotoxin - fluoride.

Like that kid that a “clock”.🙄
That filter idea is a wonderful innovation. But these idealists are about to get a hard lesson in market capitalism.
Overhead, fellas and gals: overhead.
