| There
is a saying that necessity is the mother of invention. What that
means is when a need arises, some one will find a way to satisfy that need.
When Ladislo Biro grew tired of his fountain pen leaking all over him and
smudging his paper, he can up with a way to keep clean -- the ball point
pen. This is the story of young Dotty who is an inventor. As
she tries to figure out which of her inventions to enter into a contest,
we find out about many real inventions and how they came about. |
