Introduction: Portable Device to Turn Plastic Bottles Into Rope
Plastic PET bottles at the end of their shelf life usually face two options :
- They are either thrown away at the landfills (which is a threat to the environment) or
- they are recycled (better option than the landfill).
But there is a third option (far better in my humble opinion) which is reuse. These containers can be reused in a lot of fun and creative ways and I am sure that www.instructables.com already has many instructables for that.
One thing that you can make out of a plastic bottle is rope. This kind of rope is quite strong and has heat shrinking properties.
I tried making some contraptions in the past to cut pet bottles to produce string. The results were poor. Either the contraption was bulky and required a table or a vice to secure it in place or the string jammed somewhere during cutting and broke.
After many prototypes I made a device which is simple, efficient and portable. You can have it with you in a backpack, in your car or in your zombie apocalypse survival kit ;-).
Step 1: Gather Some Materials
For this instructable you need :
- a rectangular piece of wood
- a Phillips screwdriver
- some metallic strapping tape (see above photo)
- a paper cutter blade
- 4 wood screws 1.5 cm in length
- a hacksaw
- resin paper
Choose a piece of wood that can easily fit in your hand. Mine is 4.5 x 4.5 x 17 cm.
Step 2: Assembly
You will have to make two slits as noted in the above photos. I used a hacksaw for that because it has a slim blade.
Continue, installing the metallic strapping tape pieces and fasten them at the wood with the screws. Their purpose is to hold the blade in place.
Step 3: Let's Make Some Rope!
Make a pilot cut at the bottom of the bottle and insert it in the device as shown in the picture.
Grab the protruding piece and pull it using your hands or pliers. Continue pulling until all the bottle is consumed.
The rope that comes out has width 0.5 cm. If you want, you can make multiple slits for multiple rope widths.
Step 4: Using Your Rope
You can use your rope in the garden or anywhere else you need to tie things up.
This material shrinks and hardens when heat is applied so you can fasten things extra tight.
