  Plastic in brain from cans? Cans made of aluminium. I am confused. 🫤

    There’s actually a thin plastic membrane on the inside of most cans. It helps preserve the taste of the product. There’s a couple cool chemistry videos on YouTube where they use acids to dissolve the metal without damaging the plastic, leaving a weird bag of soda with a can lid.

      Also how we can have liquids in cardboard boxes. People are very confused by that.

      There is also the one where you use a bent wire to score the plastic liner on the inside of the can then put the acid in the can and swirl it around and pour it out. This leaves the can looking perfectly normal but makes it so you can easily rip the can perfectly in two to the amazement of your chemistry students.
