The toy industry is incredibly competitive. Before the fall of Toys R Us, inventors would clamor over the very limited toy space available to them. If you were lucky enough to win a coveted spot on the store shelf you were already ahead of the game. If your toy became successful, untold riches awaited you.
These toy inventors created some of the most popular toys in history and in the process they became millionaires. From rocks made out of toys to a billion-dollar idea created by a former NASA rocket scientist, these toys made their inventors wealthy beyond their dreams.
The Slinky is a $250 million toy invention that was created by accident. The toys inventor, Richard James, came up with the idea for his Slinky toy after he dropped a tension spring on the floor and noticed how it flopped around.

Today, he funds his own research company that aims to revolutionize the electrical power generation and storage industries.

Snap Bracelets have been recently making a comeback, not bad for a toy that became popular in the early 1990s. The idea of this toy/accessory is simply, you slap a long piece of fabric on your wrist and it transforms into a bracelet.

Silly Putty was invented by James Wright while he was working at General Electric's New Haven, Connecticut lab in 1943. A rubber shortage caused by Japan invading various rubber producing countries led to US efforts to invent synthetic rubbers. Nutty Putty, as Wright originally called it, didn't work for its original intended purpose.
Several years later, Wright borrowed enough money to secure the production rights for what he rebranded as "Silly Putty." He hired Yale college students to place the putty into one-ounce red plastic egg containers which he sold for $1 each. By the time of his death in 1976, Wright was worth an estimated $140 million.

The product was originally marketed for the sport "footbag" which specifically uses the brand name product for events held at locations around the world. The hacky sack is either a toy or a serious sports accessory, depending on who you ask.
