“To invent, you need a good imagination and a pile of junk,” Thomas Edison once said. Well that certainly applies to these homespun oddities.

From a bi(ke)plane to a 'helicarptor', these amazing homemade inventions are examples of human ingenuity and, possibly, boredom.

As Agatha Christie once said “I don't think necessity is the mother of invention. Invention . . . arises directly from idleness, possibly also from laziness. To save oneself trouble.” 

You nailed it, Agatha!

Which of your own inventions are you most proud? Which one of these inventions do you think you could put to good use?
