Discoveries in space plasma may provide an explanation for a century-old mystery. Sir William Armstrong, an English hydraulics engineer, first observed the floating water bridge in 1893. It defied explanation and was ignored until recently. Findings in space plasma that have renewed attention to plasmaÕs electrical properties, a matter which itself has been neglected for a century, may provide an explanation that has been sitting in plain sight all along.

A water bridge is simple to produce. Two containers of pure water are set an inch or less apart. An electrode is inserted into each one, and a high voltage is struck between them. In short order, a spinning tube of water will stretch across the gap in defiance of gravity. While the phenomenon and its possible explanation are interesting (and may be pursued in the links), this writer will for a moment prescind from the science and comment instead on the century of neglect.

Navigable aqueducts (sometimes called water bridges) are bridge structures that carry navigable waterway canals over other rivers, valleys, railways or roads. They are primarily distinguished by their size, carrying a larger cross-section of water than most water-supply aqueducts. Although Roman aqueducts were sometimes used for transport, aqueducts were not generally used until the 17th century when the problems of summit level canals had been solved and modern canal systems started to appear. The 662-metre long steel Briare aqueduct carrying the Canal lateral a la Loire over the River Loire was built in 1896, and remained the longest navigable aqueduct in the world until the 21st century, when the Magdeburg Water Bridge in Germany took the title.
