T-Rex: Today is a good day I think to talk about phlogiston!
T-Rex: That's right! Phlogiston, bitches!
T-Rex: Phlogiston was proposed as a scientific explanation for combustion! It was clear that some things burned (like wood), while other things would not burn (like ash). Phlogiston was a colourless, odourless and weightless substance that was contained in things that could burn. When they burned, the phlogiston was released into the air!
Utahraptor: That's a pretty crazy theory!
T-Rex: Yeah, but it totally worked for a while!
T-Rex: It explained why if you burned things in a jar, they would go out: the air can only hold so much phlogiston! But it started to fall apart when people discovered that some things, like magnesium, actually gained mass when burned.
Utahraptor: So phlogiston would have to have a negative mass!
T-Rex: Yeah! That seemed a little TOO krazy. But it's actually pretty close to what we now believe, only backwards!
T-Rex: (We believe materials are deoxygenated and become oxygenated when burning!)
Off panel: Man! I know it!!
