Crash course - chemistry

The Green boys are outstanding.

There's almost nothing else to be said about them - between the novels, the magazine, and the various YouTube channels, they've offered up a lifetime of intelligent entertainment already and show no signs of stopping.

And their Crash Course series (in chemistry and fourteen other topics) are wonderful introductions (if sometimes a little quickly spoken) to the topics, and the graphic style and illustrations help to augment their explanations.

Well worth your time, but I will warn you that they present their information thoroughly and rapidly. Be prepared to watch through a couple of times if you're not already somewhat familiar with the topic about which they are elucidating.
