To make tire tube bungy cord there are very few materials needed. these materials include:
*one or more tire tubes
*4 S hooks per tire tube
*a sharp pair of scissors
*a srong needle or pin (I used a sharp dental tool)
Step 1: Cutting the Tire Tube
The first thing you do is cut of the section of the tire tube containing the valve stem. This piece can be used for another project, or just discarded. After this has been completed fold the length of your tire tube in half and cut it down the center.
Step 2: Puncturing the Tire Tube for the S Hooks
The next thing that you need to do is pinch the end of your tire tube between your thumb and fore finger, then fold the end in half. now you take your pin and push it thruogh the tire tube in the center about a half inch away from the end.
Step 3: Insertng the S Hook
The last step is to take the end of your tire tubes and S hooks, and while streching the hole open with on hand and insert the Shook withe the other. This can be a little hard and may take more than one attempt. after you have done this for one side repeate it for the other. When this is complete your tire tube is done.
Step 4: Modifications / Alterations
*cutting your tire tube longer or shorter
*using larger or smaller S hooks
*using a car inner tube for more resistance
warning: The over stretching of tire tubes may result or a break, or tear. so always be catous when stretching the tire tubes.
