Fahlberg continued with his meal,
soon realizing it wasn't just the roll that was sweet, it was everything his hand touched.
When working with chemicals, most of us would take care to wash our hands before eating, but in 1879,
Constantin Fahlberg forgot.
On one particular day, after working in the lab, Fahlberg was at home,
about to tuck into his meal, when he noticed that the bread roll he would just taken a bite out of tasted incredibly sweet.
