Introduction: Cheap Shock Cord

I'll tell you how to get shock cord for cheap!

Step 1: Obtaining Cheap Shock Cord

It happens to all of us. We build an Esties model rocket, launch it a dozen times and then the shock cord gets ripped/burned. Esties sells replacement cord for $$. Many people don't realize that shock cord is actually 1/4" elastic, which you can purchase at any fabric store. Better yet, it's available in the sewing/craft section of your local Wal-Mart.

Yeah and you can get rubber bands in so many different sizes. I once used one from a punch balloon I had lying around it was long and lite. Another good one is cut a peice of plastic bag roll it up and torch it lightly with lighter so it binds together. I think the latter is actually lighter than the rubber.

I dont know how many times I've had to replace the shock cord on my rockets. I try to use things that i dont have to buy. I've learned that one of the cheapest ways is to make one is take a shoelace and tie a bunch of slip knots in it. Its worked pretty well for me

Heck you could even use the Elastic out of some old underwear now that would really be saving!

that idea was on mythbusters

In Xena (the rocket held in the group photo), we used a small bungy chord. It worked very well concidering it was 1) strong, 2) had premade metal ends to attach to the bulkhead and spring.
