Fountain Erupts Every Time You Turn It Over!
Make gushing fountain with two empty plastic soda bottles and this Fountain Connection!
Hero of Alexandria (ca 62 AD) described a water fountain that used compressed air to lift water to a point higher than its origin. The result was a fountain the seemed to defy both logic and the laws of nature. A closer study of your fountain will reveal the principles of operation.
When the bottles are inverted, gravity pulls the water from the upper bottle down through the lower tube and compresses the air in the lower bottle. When water leaves the upper bottle, a decrease in pressure, or partial vacuum is formed. Air is them forced from the lower bottle, up the fountain tube, and takes the place of the water as it leaves the upper bottle.
Made in the USA. For ages 5+.
