"interactive" Water Applet by Anfy
Most people know that Thomas Edison
conducted countless
experiments with countless kinds of materials in search
for an effective filament to use in carbon incandescent
lamps. As each fiber failed, he would toss it out the
window. Ultimately, the pile of failures reached to the
second story of his house.
Edison's Menlo
Park Home
One day in l879, some thirteen months after his first
failure, he succeeded in finding a filament that would
stand the stress of electric current. Here's how:
Edison casually picked up a bit of lampblack, mixed it
with tar, rolled it into a thin thread, and thought,
WHY NOT TRY A CARBONIZED COTTON FIBER? He worked for 5
hours to make a fiber but it broke in two before he removed
the mold. He used two spools of cotton thread before a
perfect strand emerged, only to be ruined when he tried
to place it in a glass tube. He continued without sleep
for two days and nights before he managed to slip one of
the carbonized threads into a vacuum-sealed bulb. Turning
on the current, he saw the glow of electric light that we
now take for granted.

A FAILURE DOESN'T NEED TO MARK THE END.
IT CAN BE ONE STEP CLOSER
TO THE SUCCESS YOU DESIRE!
