That kind of a mouse wasn’t used by anyone except for the people that conceptualized the mouse. When the GUI matured a mouse became necessary but the first mass produced one looked a lot like what we have today except it had a ball on the bottom side and it was wired. In before “thanks boomer.”

"In the 60's of the 19th century" made me laugh on the vacuum one. Really that hard just to say 1860's?

Air conditioner

Many attempts at air conditioning have been made throughout the entire history of humanity. In 1842, American doctor John Gorrie invented the prototype of the modern A/C — a compressor for cooling down the air that he used in the wards of his patients. Unfortunately, he didn’t have enough money to produce these machines. But other inventors supported his idea and in 1902, the first electric air conditioner appeared.
