Weird Inventions and Technology
Which of these odd household objects was actually patented and marketed as a legitimate invention in the early 20th century?
Correct
The baby cage was a very real, albeit terrifying, invention patented in the 1920s to ensure babies in cramped cities got fresh air. As for the others, coal-powered toothbrushes never existed because that sounds like a dental disaster waiting to happen. Hydraulic buttering toasters are pure imagination and would likely just make a greasy mess of your kitchen. Lastly, an explosive umbrella would be a hilarious safety violation, so humans thankfully never actually tried to market that as a household necessity.
