Experimenting on a raft anchored on the river Elbe, Alfred Nobel tries to make nitroglycerine safer to handle. Finds that the addition of kieselguhr turns nitroglycerine into a dough that can be kneaded, and calls it "dynamite".

Alfred Nobel works with dangerous chemicals but that doesn't make him unsafe around children. He could be or he couldn't be which makes it neither correct nor incorrect.
