Here are some one liners...
The Diamond Necklace Affair or How to Destroy a French Queen -- A con artist destroys the reputation of the Queen of France. This is one element for the beginning of the French Revolution.
Steam-Powered Locomotion and the "Puffing Devil" -- It is a steam carriage... just a model. I talk about the beginning of a steam-powered railroad.
Other Important Events -- Puddling wrought iron, bifocals and the Argand lamp.
The Diamond Necklace Affair or How to Destroy a French QueenJeanne is a con artist who orders a diamond necklace and sends the bill to the Queen. The Queen denies ever ordering the necklace, and accuses Cardinal de Rohan of a plot to discredit her. (She and the Cardinal often fought at court.) How did it all happen? Jeanne claimed to be a descendant of one of the kings of France. She had been sleeping with Cardinal de Rohan and convinced him that the Queen wished him to purchase a diamond necklace on her behalf. When the bill came, the Queen denied ever purchasing the necklace. The Cardinal insisted that she did, pointing out that the Queen was standing before him when she did. (It was an imposter than Jeanne arranged.) In the end, the Queen is exonerated but so is the Cardinal. In the public's eye, she looks like a self-involved knucklehead. More importantly, any future rumor, no matter how fantastic, is now believed. Thus when the people are starving from lack of bread, they believe the rumor that she said, "Let them eat cake!" Could it ever be worse? Why yes. It could be and will be.  
Steam-Powered Locomotion and the "Puffing Devil"It is a "steam carriage" or "road locomotive." No rails involved. (Don't be silly. Rail cars are pulled by horses!) William Murdoch is the man who helped James Watt improve the Boulton-and-Watt steam engine. He rearranged the gears and increased the efficiency. Murdoch's basic steam engine design is still used in the modern day for some applications, but he is best known for his experiments with the first locomotive and for gas lighting. His first locomotive is just a model about 2 feet tall, but that oscillating steam cylinder that goes "chug-a-chug" with an arm attached to a wheel is his invention. When you see it, you know. That is part of a locomotive.   
Other Important Events
- Benjamin Franklin invents bifocal glasses. It seems that he invented them independently from others who also invented bifocals. The term "bifolocal" won't come into use until much later. 
- The 'puddling process' for making wrought iron is patented. The process needs improvement but they are on their way!
