Imagine that a man named Robinson Crusoe lives on a deserted island. His main source of food is coconuts. He works for most of his day shimmying up trees to get coconuts to eat. One day he thinks of a new invention—a coconut picker. He ties some long pieces of bamboo together with a rock at the end to knock down the coconuts. Now he no longer has to spend hours climbing trees to reach the coconuts. He gets twice as many coconuts a day and has more free time to work on building a boat to escape the island.
