Mary Anderson's Great Invention

Because cars did not have windshield wipers, 

• people cleaned their windshield with an apple
• drivers ate a lot of onions. 
• people cleaned their windshield with an onion. 

Mary was cold and wet...

• so she went home
• so she rode the streetcar in New York
• so she put on a big coat
• so she invented the windshield wiper

The streetcar drivers pushed the window open to see the road, and

• as a result, snow and ice blew in his face. 
• as a result, he put on goggles.

Cars kept stopping to wipe off their windshields and, 

• as a result, people walked to work. 
• as a result, the traffic moved slowly.

Mary thought of the drivers problem 

• then, she sketched out her idea.
• then,  she did some investigation.
• then, she came up with the design.
• all of the above

Not many people owned a car and 

• as a result, they forgot about Mary.
• as a result, windshield wipers were very popular. 
• as a result, it took a year for people to start using them.
