Did ya Know?
In the 1960s, 3M scientists were hard at work researching an alternative
to carbon copy paper and subsequently invented a technique known as
micro-encapsulation. The process of micro-encapsulation allowed
researchers to make ink copies without carbon copy.
Eventually scientists began using this process for perfume testing
strips in 1981.
Introduced just after
Tinkertoys and the Erector Set, Lincoln Logs were yet another construction toy to make it
big during the early 1900's!
John Lloyd Wright, son of architect Frank Lloyd Wright, brought out
the line of sturdy, interlocking logs in 1916. Wright claimed that the foundation of
Tokyo’s earthquake-proof Imperial Hotel, which he saw while it was under
construction, inspired the shape of his logs.
Jigsaw Puzzles
Englishmen, John Spilsbury invented
the jigsaw puzzle in 1767. Spilsbury was an engraver and mapmaker. The
first jigsaw puzzle was a map of the world. Spilsbury attached a map to a
piece of wood and then cut out each country. Teachers used Spilsbury's
puzzles to teach geography Students learned their geography lessons by
putting the world maps back together.
