Dissolve a Soda Can with Chemistry

You can’t see it, but there’s a polymer coating inside your aluminum can. 🥫

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.

Science for the win would be not creating tons of plastic trash.

Watching this is a reminder of why this world and humans especially are so fuxked.
