| Narrator:
AN 1880s INVENTION, |
00:00:53.152 - 00:00:55.154 |
| THE CAST-IRON TUB
WAS FIRST MARKETED IN AMERICA |
00:00:55.154 - 00:00:58.191 |
| AS A HORSE TROUGH
AND A HOG SCALDER, |
00:00:58.191 - 00:01:00.660 |
| WHICH COULD ALSO SERVE
AS A BATHTUB. |
00:01:00.660 - 00:01:03.095 |
| IT WAS SOON MORE POPULAR IN
THE BATHROOM THAN THE BARNYARD. |
00:01:03.095 - 00:01:06.599 |
| IT'S HEAT-RETAINING PROPERTIES |
00:01:06.599 - 00:01:08.401 |
| MADE A LONG AND LUXURIOUS SOAK
POSSIBLE. |
00:01:08.401 - 00:01:11.371 |
| THE CAST-IRON TUB
IS ONE INVENTION |
00:01:15.141 - 00:01:18.077 |
| THAT'S GOT A LOT OF PEOPLE
IN HOT WATER, |
00:01:18.077 - 00:01:20.045 |
| AND THAT'S WHAT PEOPLE LIKE
ABOUT IT. |
00:01:20.046 - 00:01:22.649 |
| TODAY, THEY MAKE CAST-IRON TUBS
FROM SCRAP METAL -- |
00:01:24.917 - 00:01:28.487 |
| THINGS
LIKE OLD HEATING RADIATORS, |
00:01:28.487 - 00:01:31.223 |
| WATER PIPES, MANHOLE COVERS,
AND EVEN SOME CAR PARTS. |
00:01:31.224 - 00:01:35.528 |
| RECYCLING SCRAP IRON |
00:01:38.631 - 00:01:39.999 |
| IS MORE ENERGY EFFICIENT
AND CHEAPER THAN MINING IT. |
00:01:39.999 - 00:01:43.369 |
| A POWERFUL MAGNET
AT THE END OF A CRANE ARM |
00:01:45.305 - 00:01:48.007 |
| LIFTS THE HEAVY IRON
FROM THE SCRAP HEAP |
00:01:48.007 - 00:01:50.543 |
| AND TRANSFERS IT |
00:01:50.543 - 00:01:51.611 |
| TO BIG TRAYS
KNOWN AS CHARGING PANS. |
00:01:51.611 - 00:01:54.380 |
| THE CHARGING PANS DELIVER
THE SCRAP TO A CENTER TROUGH. |
00:01:56.348 - 00:01:59.819 |
| THIS TROUGH IS A SCALE. |
00:01:59.819 - 00:02:01.287 |
