Bifocal Glasses Bifocals are eyeglasses with an upper and lower half, the upper for distance, and the lower for reading.

Electricity Franklin did not invent electricity but he discovered many things about it. He showed that electricity consisted two opposing forces. He also showed that electricity consisted a common element which he named it the electric fire. Further, electricity was "fluid" like a liquid. It passed from one body to another — however it was never destroyed.

Lightning Rod Once Franklin had an understanding of the behavior of electricity, he set about to protect houses from the destructive forces of lightning. A lightning rod, simply, is a rod attached to the top of a building, connected to the ground through a wire. The electric charge from lightning strikes the rod and the charge is conducted harmlessly into the ground. This protects houses from burning down and people from electrocution.

Franklin Stove In America homes were warmed by a fireplace. The Franklin Stove, invented in 1742, is a metal-lined fireplace that stands in the middle of a room. It has rear baffles for improved airflow. It provides more heat and less smoke than an open fireplace and uses less wood. The cast iron furnace radiates heat from the middle of the room in all directions and the iron walls even observed warmth to the room long after the fire went out.

Swim Fins Benjamin Franklin was an avid swimmer from a very young age. Throughout his life he consistently promoted its healthful benefits. At the ripe old age of 11 he invented a pair of swim fins. However, unlike today's foot flippers, these were attached to one's hands. His advocacy for swimming was recognized by his induction into the International Swimming Hall of Fame in 1968.

Glass Armonica A popular entertainment in England in the early 18th century was playing music on upright wine goblets, with tones made by rubbing one's fingers around the lip of glasses filled with different quantities of fluid. In 1761, Franklin created a mechanized version, and called it the Armonica (after the Italian word for harmony.) Franklin worked with London glassblower Charles James to build his Armonica, and it had its world premiere in early 1762, played by Marianne Davies. Franklin's foot-treadle-operated instrument held 37 glass bowls. The musician touched the rims of the bowls with fingered moistened from the water trough. The bowl-rims were color-coded, according to the note. For example, C's are red, D's orange, E's yellow, etc.

Odometer Franklin was curious as to how far he was traveling by carriage, in his role as postmaster, for his travels between Philadelphia and Boston. While the concept of the odometer dates back to ancient times, Franklin did create his own version. The concept was to attach the device near the wheels of a carriage, determine the circumferance of the wheel and the number of revolutions required to travel a mile, and have the device register the distance traveled.
