And Away We Go: Rockets
A New BRIGHT Idea
Computers LARGE and SMALL
The Inventions Examiner
Rockets were first invented in the 1200's by the Chinese. They were made by putting gunpowder in a tube. Robert Goddard then took the idea to a whole new level after building a rocket to carry "earthlings" into space. 39 years later Neil Armstrong took the first step on the moon. Goddard became interested in rockets when he climbed a cherry tree and looked into the sky. But Goddard had to keep the rocket building as a part time job since rockets were considered "un-scientific". A circumstance where rockets were used were in the War of 1812, causing Francis Scott Key to write about the "rockets red glare."
The laser was invented by Theodore Maiman in 1960. He based it off of the work of Charles Townes and Arthur Schalow.
The first calculator was CONCEIVED in the 1830's by Englishman Charles Babbages, but the first ACTUAL calculator was invented in 1945. It was called the E.N.I.A.C. (Electrical Numerical Integrator and Computer).
American, Howard Aiken is credited with the first computer, created sometime after WW11. The computer was named the Harvard Mark 1- it was GIANT! It measured over 48 feet long and was filled with over 5,000 vacuum tubes. A vacuum tube boosts electrical current that would otherwise fade away.
The transistor, created in 1947, is a replacement for the vacuum tube because it is cheaper and more reliable.
The Popsicle was invented by 11 year old Frank Epperson in 1905. He made soda using soda water powder and water. He left the cup of soda outside overnight with the stirring stick still in the cup and the soda water froze. In 1923 (18 years later) Epperson remembered his frozen soda and began a business. He created fruit flavored "Epsicles" that was later changed to the name Popsicle.
How the Popsicle was invented....
Georges de Mestral
In 1948, Georges de Mestral took a walk in the woods with his dog. He noticed how burrs stuck to his clothes and the dogs fur. He studied one under a microscope. He saw the burr's barbed seedpods that hooked onto the fibers in his clothes. De Mestral made nylon hooks and loops that looked like the burrs' barbed seedpods. He called his invention Velcro. The word Velcro came from the French words velours (velvet) and crochet (small hook).

Inventions and Inventors
Here is a picture of one of the first cars ever invented, The Model T. The Model T was invented by Henry Ford in 1908. He made cars cheaper using the assembly line. The Model T sold for around $ .
Logan Conley & Mandy Orgler
Thomas Edison is most famous for his invention of the light bulb. But he also invented, moving pictures, the voice recorder, and improved the telegraph. He had 1,093 patents in his lifetime.
*Patent: a government authority or license conferring a right or title for a set period, esp. the sole right to exclude others from making, using, or selling an invention.
Uses of the laser...
1. They are used in grocery stores to scan barcodes
2. They can cut through metal
3. They can perform medical miracles
4. The military created a "smart bomb", or missile in 1967, using lasers to guide it.
5. They can scan CDs in CD players to play music and movies.
