Explain in detail how a volcanic eruption in 1816 led to an invention you have known since you were two!

Explanation:

The most destructive explosion on earth in the past 10,000 years was the eruption of an obscure volcano in Indonesia called MountTambora. More than 13,000 feet high, Tambora blew up in 1816 and blasted 12 cubic miles of gases, dust and rock into the atmosphere and onto the island of Sumbawa and the surrounding area. Rivers of incandescent ash poured down the mountain’s flanks and burned grasslands and forests. The ground shook, sending tsunamis racing across the JavaSea. An estimated 10,000 of the island’s inhabitants died instantly.
