While working in the lab, he spilled a chemical on his hand. Later while eating dinner, Fahlberg noticed a more sweetness in the bread he was eating. He traced the sweetness back to the chemical, later named saccharin, by tasting various residues on his hands and clothes and finally chemicals in the lab (not a safe lab practice). Saccharin is sold under the Sweet'N Low, Sugar Twin names.
