A Coca Colas Can secret revealed 😱
Still think aluminum cans are better than plastic? Buff the top layer of paint off of an aluminum can. Open the can and use a wooden rod to suspend it in a suitably sized beaker. Add some drain cleaner. Observe a tumultuous reaction and release of gas. Wait two hours. Take the can out of the liquid. It would seem as the aluminum has completely dissolved, but the drink hasn’t leaked out! The ordinary aluminum can is concealing a devious secret. It is covered with a protective layer on not only the outside but the inside as well! When the paint coating is removed, the aluminum is exposed, which easily reacts with a drain cleaner that contains an alkaline component. But even when the aluminum has dissolved completely, the drink will not leak out. There is a second material inside the can- a layer of plastic that keeps that keeps the drink itself from interacting with the aluminum. 😱😳 #savethefishies #sandcloud #melscience
