You can’t see it, but there’s a polymer coating inside your aluminum can. 🥫
In this episode of Science Experiments & Demonstrations, @chemteacherphil uses chemistry to prove it! Working with lye, which is highly caustic and requires proper safety equipment (so please don’t try this one at home), he makes a solution that reacts with the aluminum, converting it into a compound that dissolves in water. When the aluminum is gone, you can see the polymer coating! These coatings are useful because without them, acidic drinks could slowly corrode the aluminum underneath.

Chemteacherphil x Museum of Science:
Among the world’s largest science centers and New England’s most attended cultural institution, the Museum of Science reaches over 300 million people a year — at Science Park and in museums around the world, in classrooms, and online. Established in 1830, the Museum is home to such iconic experiences as the Theater of Electricity, the Charles Hayden Planetarium, and the Mugar Omni Theater. The Museum influences formal and informal STEM education through research and national advocacy, including through its Youth Exploring Science (YES) program through the William and Charlotte Bloomberg Science Education Center. Around the world, the Museum is known for digital experiences such as Mission: Mars on Roblox and traveling exhibitions such as Science Behind Pixar. The Public Science Common, a state-of-the-art programming and event space featuring sweeping 270-degree views of Boston and Cambridge, and is a space to bring together people for a wide variety of programs and events.

I recycle my cans, and last time I was there to do so I mentioned how the inside is actually plastic on most cans.
They looked at me insane and like smirkingly said ‘no dude it’s not’ three different guys.
Yes dude, they are.
Haven't we been canning drinks longer than plastic has been around? Why can't we just go back to doing it the old way?
Barbecue beer can chicken
False advertisement! Sir, you in fact, did lye
So no wonder people die of micro plastics
Success, but I feel like there are ways it could have failed or been unsafe.
So cool — no lye!!
Boy I wonder what brand of soda that might be….
It's also plastic for the L😒.
It needs it to avoid the aluminium oxidising.
all cans which contain food have a polymer coating, that is why I always scream when "survival" channels heat their canned food in the can over an open flame
Liquid Death: “Death to plastic” 😂😂😂
The cans are laminated, right?
This has been done a dozen times on other YouTube channels…. Seen it, been there, done that.
So how do they get just the aluminum when the cans are recycled???
I think the greatest problem is not that can but the people that buy bottled water. Unless you have bad water from your tap there is no reason to destroy the environment for your microplastic filled water. Most water in those bottles is just tape water filtered and then they often add back minerals.
Micro plastics are in cans!
apparently canned pineapple juice is one of the last tin canned things available today
I hate drinking out of cans. You can taste both the plastic and the aluminum. They ruin the taste of nearly everything in them. I prefer glass. its chemicaly inert and tastes like nothing
"not gonna lye" a likey story
Microplastics EVERYWHERE! 💀
Tell that to the kombucha can that decided to short circuit the other day in my cabinet
Bpa and microplastics as far as the eye can see.
How can you be sure when you used lye?
Stainless steel, glass, ceramic and silver are the only food safe containers
When did they add the polymer coating. I saved a can of classic Coke from 1985 and noticed by the early 2000s that the syrup inside had leaked all over the place.
Thank you
The bottom of the can is where it was originally formed from and is SIGNIFICANTLY thicker than the walls, so to dissolve it, it would need more time
There are microplastics in the Amazon rivers, and in the global rainwater
^ for all the martyrs in the comments who have never drank Diet Coke apparently
Companies have already screwed the pooch on this one…. what we need now is a safe filtration technology or something
And microplastics are also in aluminum can drinks
Another reason to not drink soda, much less out of a can.
Diffusion happens with fully plastic soda cans that is interesting… Gas and pressure basically leaks into plastic and outside. Slowly but measurably.
Aluminum prevents that.
….then you go into semipermeable membranes…osmosis…molecular sieves and potassium pumps and then you remember those for three years and kinda forget it and parrot those words around in your head….
As no true understanding is born of it… unless you truly think about it still would have to have electron microscopes at least good optic microscope… And stuff and devices to manufacture different sieves and chemicals and magnetic materials and magnets and magnetizing machines.. oscilloscope..
Some of them can be basically build from scrap but can't afford rent so who cares.. goldfish attention span is… Shiny.
That is an awesome reveal! I love when the soda leaves the can the plastic instantly shrivles up
