2 Empty Water Bottles w/caps for the handles.
Scrap Paper (Newspaper, Color Paper, etc.) for the inside of the bottles as weight and for the paper rope.
Super Glue (Not Needed but Recommended)
Step 1: Step 1: the Caps
Step 2: Step 2: the Paper Rope
When the strip is folded into a good size, twist both ends to a point so that they can go through the holes in the caps.
Step 3: Connecting the Paper Rope to the Caps
For the other cap thread it through from the top part. Also leave a good length for a knot.
Tie a knot on both sides so that the rope is secure.
Use the super glue on the knots and/or glue the cap and knots together.
Step 4: Step 5: Stuffing the Bottles
How much depends on your preference.
Step 5: The Final Step and Usage
After that you are ready to go to fight crime and pollution as an Eco-Ninja.
If the chord breaks you can recycle the materials or make a new paper rope.
