#39: Playing with Fire
With all of our new technologies and devices, we’ve gotten pretty clever and advanced as a society. But you also have to be a little impressed with our ancestors, who had fewer technological solutions available at their fingertips, so they sometimes had to get really creative to fix their problems.
For instance, look at this old fire door. The weight drops if the rope catches fire, causing the door to slide down the slanted tracks and into place. Of course, if the fire is close enough to the rope to catch it on fire, it’s probably close enough to go through the doorway. But still, it’s ingenious.
