Zip Line Made With Kevlar String !

As you may know, the Iron Man EDF flight system has been the central project around Hacksmith Industries for quite some time now. In the meantime, the crew could use a fun project once in a while to blow off some steam, and James needs to log some flight hours in preparation. Zip lines are easier than outright flight and still super fun, so the team has set about installing a zip line that runs from the back of the workshop to the derelict princess castle at the far end of the lot.

The zip line itself is made from kevlar string, rated up to about 2000 pounds of tension.  Some quick math suggests that with James flying along, the string will sag about five feet, and the resulting tension will be about 1800 pounds – 200 pounds shy of breaking while James’ body is on the line. Not exactly a safe margin for error, right?

Kevlar Zip Line Just DO It

That settles that. I guess it’s time to set it up and test it out.

The first attempts ran into a few –literal– snags, but obstacles in the runway aside, the zip line works and is as fun as expected. Still, that’s not quite enough for Hacksmith Industries. Sometimes, you still have to up the ante. How would a Hacksmith go about doing that?

Fire. Fire is the answer, obviously. Would zip lining THROUGH fire be cool? Trick question — but you get bonus points for trying! The correct answer is it would be freaking awesome.
