Not so much as the poster of this video found out, so he decided to create a periodic table rap of his own. Take a listen. The chemical rap was created by YouTube user "Oortkuiper" who writes ...

At the moment physicists are having enough difficulty just taming antihydrogen, the simplest possible anti-atom. Can we ever expect them to make a whole anti-periodic table?

Physicists have created the heaviest clumps of antimatter particles ever seen. Known as antihyperhydrogen-4, this strange stuff could help us solve some of the most puzzling physics mysteries.

Imagine that Superman's opposite-in-all-ways enemy, Bizarro, taught high-school chemistry. (Bizarro does enjoy inflicting punishment, after all ...) What sort of periodic table would hang on the wall ...
