THE LIGHT BULB

Today’s Inventoon is – oh, I know – the light bulb. Before the electrical light bulb people had to use candles and lamps if they wanted to see in the dark... and unfortunately this sometimes led to a few problems.

Thankfully, in 1879, the famous inventor Thomas Edison came up with the solution. He put a piece of thread - coded in carbon – between two wires, and put the whole thing into a vacuum-sealed glass bulb. When he added electricity, the current, going through the filaments, causing it to glow. Of course, not everyone was happy about this! : - )
