Did You Know?


The use of vinegar on calcium "just like Hannibal" references the story of how Hannibal's engineers, while crossing the Alps, heated boulders that blocked their way with wood fires, then poured vinegar over them. The rocks, weakened by the heat, were broken up by the vinegar into smaller pieces, which were then easily moved to clear a path. See more »

A disappointing 2nd part
5 April 2020 | by warlordartosSee all my reviews

I think they should have just made a 1 hour special with this one and last weeks episode. Lots of filling done in here and dragged right out in order to get the full 40+ min show time.

Sorry the writers just went too far on this one.
