Top 10 Inventions that Changed the World

6. Light bulb

Imagine a world without light bulbs. This world will be darker and might be very primitive with the use of fire as a source of light. Thomas Edison is credited to have invented the light bulb but again, there are those people who also work at the same project at that time. It was only Edison who made it first available commercially. Because of the light bulbs, our streets and homes have been safer and brighter.
