Scientist Breaks Down Chemistry in Iconic Cartoons - SpongeBob, Popeye, and Who Framed Roger Rabbit

People have been developing different forms of shark repellent for decades, the military even issued a chemical shark repellent called “Shark Chaser” to pilots, sailors, and astronauts(!) from the end of World War II through the start of the Vietnam War. Thing is… it didn’t really work. Learn why they bothered passing it out, or even created it in the first place.

Watch an overview featuring a demonstration of a burning candle as an example of a chemical reaction. A molecular animation shows that the atoms in the reactants come apart from one another, rearrange, and re bond to form the products.

There are tens of thousands of mushroom species out there, and some of them could kill you. Today we’re going to test how well you can separate the perfectly safe from the perilously poisonous, and dive into the chemistry behind what makes seemingly identical species so different.
