In this week’s fun facts edition: The Lightest Rock, The Invention of the Chocolate Chip Cookie, Sports Invented at the YMCA, Artificial Reef Subway Cars, and The First Electricity at the White House.
The Lightest Rock
The only rock that can float in water is pumice. Pumice is lightly colored volcanic rock that is highly porous. It’s formed when lava from a volcano cools rapidly, making it about 90% porous. Pumice is used in construction as an additive for cement, and it’s also used as an abrasive.
In 2012, a large island of pumice was found floating in the South Pacific. It was more than 300 miles in length and 30 miles in width. It was believed to be caused by an underwater volcano somewhere along the seafloor. Source, Source
The Invention of the Chocolate Chip Cookie
It’s one of the most popular desserts of all time, but where did the chocolate chip cookie come from? The chocolate chip cookie was invented by Ruth Graves Wakefield at her Toll House Inn restaurant in Whitman, Massachusetts in 1938.
The invention of the chocolate chip cookie by Wakefield has been portrayed as an accident, but that doesn’t seem to be the case. The Toll House Inn restaurant that Wakefield ran with her husband was very popular, and she had a college degree in home economics. Wakefield ran her restaurant carefully with an attention to detail. One myth behind the invention of chocolate chip cookies said that Wakefield ran out of nuts and substituted chopped up pieces of chocolate. But this is likely not the case since Wakefield was known for diligently running her restaurant. There is also a myth that chocolate accidentally fell into a mixer and that Wakefield decided to use the dough instead of throwing it out.
The real truth behind the invention comes from an interview in 1974 in the Boston Herald-American. Wakefield said that she had already been serving a butterscotch nut cookie with ice cream and decided to serve something different to her customers even though the butterscotch cookie was already popular. She was just trying to come up with something new to increase business to her restaurant.
Wakefield’s recipe stayed the same until 1979 when her contract with Nestlé expired. The new recipe made the cookie larger and thicker and changed some of the ingredients, but by this time, the chocolate chip cookie was already one of the most popular desserts of all time. Source, Source
The YMCA was founded in London, England, in 1844, and came to the United States in 1851. During its long history, three sports were invented at the YMCA that are still played today ; basketball, volleyball, and racquetball.
In 1891, James Naismith, a Canadian that had moved to the YMCA International Training School in Springfield, Massachusetts, invented the game of basketball. A faculty member at the school tasked the students to invent a new game that would be easy to learn and easy to play indoors during the winter. Naismith came up with a game that used a soccer ball and two goals. He made it illegal to move with the ball so it would establish teamwork during the game. The only thing he could find to make suitable goals were two peach baskets. The first game was played on December 21, 1891, and the score was 1-0 since Naismith hadn’t thought to cut out the bottoms of the baskets.
In 1895, an instructor at the YMCA in Holyoke, Massachusetts, named William G. Morgan, wanted to invent a game that had less contact then basketball. He came up with volleyball which was a mixture of baseball, tennis, basketball, and handball. He set the net to be at 6 feet 6 inches which was slightly taller than the average man .
Racquetball wasn’t invented until 1949 when a professional tennis player named Joe Sobek began playing handball with a tennis racket at a YMCA in Greenwich, Connecticut. He made a shorter racket and began to sell them to other members of the YMCA. The game soon became very popular. In 1952, tennis pro Bob McInerny came up with the name “racquetball”. Source, Source
Artificial Reef Subway Cars
The NYC Metropolitan Transport Authority from August 2001 to April 2010 dropped over 2,500 retired subway cars into the Atlantic Ocean to serve as artificial reefs off the coasts of New Jersey, Delaware, Virginia, Maryland, South Carolina, and Georgia.
After the subway cars were decommissioned, they were cleaned and anything inside them that could be taken out was removed and recycled or sold. They were then stacked on a barge which took them out to be dropped at various points in the sea. The abandoned subway cars provide new surface area and shelter for invertebrates and sea life to live where they once could not have. Source
The First Electricity at the White House
On September 14, 1891, electricity was first installed in the White House during the presidency of Benjamin Harrison. President Harrison and his wife never touched the light switches, however, because they feared electrocution.
Electric lighting was only about a decade old and a wholly new concept from gas lighting. The Edison company installed a generator that supplied power to the Navy building, what is today the Eisenhower Executive Office Building, and the wires were strung across the lawn to the White House. Round switches were installed in each room of the White House to turn the lights on and off. Source
