@museumofscience: You can’t see it, but there’s a polymer coating inside your aluminum can. 🥫 @Phillip Cook 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. #Chemistry #ScienceExperiment #LearnWithMe #STEM #Science

Interesting. The only way he could prove it was the truth was by introducing lyes!! Well, I guess it was just one container. But still.

Doesn't that mean micro-plastics

So is this contributing to our consumption of micro plastics?

It also makes them insanely difficult to recycle

If you put a full can of that lye solution could you make a boneless soda?

does that affect their recyclability?

Our clothes are made from plastic and we breath in the lint everyday. I wonder what that's doing to us.

I already knew this, but what I don’t understand is why the cans taste different than the bottles if both are packaged in plastic?!

Periodic table of videos did something similar years ago, but with two cans. One in acid, and one in base.

That’s also a great source of pfas. Just like tomatoes in a tin etc. 8g of diced tomatoes from a tin can contains the daily maximum of pfas for a child

Why didn't the thin plastic membrane pop when the can dissolved??

So what is the polymer made from, and are we consuming extra nanoplastics in a beverage that we all assumed was plastic free?

is that true for canned foods as well

This makes me wonder how they are recycling cans. Do they have to do the opposite and dissolve the polymers so they are left with aluminum? Is that even possible?
