After 500 BC, Hippocrates discovered the healing powers of water. He invented the practice of sieving water, and obtained the first bag filter, which was called the âHippocratic sleeveâ. The main purpose of the bag was to trap sediments that caused bad tastes or odours. In 300-200 BC, Rome built its first aqueducts.
In ancient history, if you needed serious firepower in a water fight, you had to reach for the hose. That changed 20 years ago when inventor and NASA scientist Lonnie Johnson came up with a way to use hand-pumped air pressure to power a water-gun blast. His Super Soaker would forever alter the way water wars are fought. While Johnson has since had a hand in (arguably) more important work, including a PM Breakthrough Awardâwinning method for generating electricity, he considers the powerful water gun to be one of his favorite inventions.
