I was fascinated by some of the crazy things people tried to get working that were discussed on that show. Things like keeping a pair of dogs, wounded by the same knife, as a way to synchronize time. As if they were some kind of quantum entangled particles.

The powder was also applied to solve the longitude problem in the suggestion of an anonymous pamphlet of 1687 entitled Curious Enquiries. The pamphlet theorised that a wounded dog could be put aboard a ship, with the knife used to injure the dog left in the trust of a timekeeper on shore, who would then dip said knife into the powder at a predetermined time and cause the creature to yelp, thus giving the captain of the ship an accurate knowledge of the time.
Should watch an old BBC miniseries, Longitude.
So much fun watching how crazy clocks are engjneered, and Jeremy irons.
