Here’s how to make a bungee jump rope using condoms: the youngsters over in this condom bungee jump explain how they made the cord using 400 M-Budget condoms. As you can see it’s a rather heavy-lifting process (and takes some family to get involved).
The video is in Swiss-German, but you don’t have to understand that much. They used condoms and some flour to make them easy to work with. However, if you want to craft a 30-metres bungee rope, it takes about 4 months and 18’500 condoms to finish (2 people). That one-way rope actually worked for Carl Dionisio, who was not that sure it would.
