If you could take one modern invention back to the 1500s, what would be the LEAST impressive to them?


  1. A treadmill. It's a device allowing you to walk but without actually moving.

  5. One of those ferrets that are attached to a ball and it has seizures when you put it on the ground. I'd put it down in front of them and be like "behold... THE FUTURE" as it silently flops around edit: spelling

  10. Any variety of seed corn that gives rise to sterile plants. "You mean you plant the corn, but you can't plant it again next year? Why would you want that?" Edit: Just a quick note to say that corn doesn't mean to me what it means to users of American English Edit 2: In British English, "corn" means [the main cereal plant grown for its grain in a given region, such as oats in parts of Scotland and Ireland, and wheat or barley in England and Wales.](https://en.m.wiktionary.org/wiki/corn). In American English it means maize, a grain crop of the species *Zea mays*. Just to make it complicated, we also mean maize when we say popcorn or corn on the cob. Edit 3: Hybrid corn would probably also work, because you wouldn't have the special inbred varieties that are used to produce the super-seeds in the first place, so you'd get crap plants starting with the second generation: > [All of the hybrid seeds planted by the farmer will produce similar plants, while the seeds of the next generation from those hybrids will not consistently have the desired characteristics. Controlled hybrids provide very uniform characteristics because they are produced by crossing two inbred strains. Elite inbred strains are used that express well-documented and consistent phenotypes (such as high crop yield) that are relatively good for inbred plants.](https://en.wikipedia.org/wiki/Hybrid_seed)
