we have many, many inventions now (obviously), things (obviously) they didn't have in 1700 or the 1800's. Which leads me to wonder; how would they react to some of out inventions now? Like the fridge. How would you tell someone from say 1788 that a fridge kept food cold and good, or a microwave cooked them with just the press of a button? Or the bus systems. Just anything technology based. What would you love to see a reaction to from someone from 1700 or 1800?
