Once you’ve wrapped the bottle all the way to the bottom you will need to cut the excess paracord.
Mark the paracord with a pen at the points where it needs to be cut. Use your scissors and cut the paracord even so that it makes it look as if the wrap continues on.
Now take you lighter and singe the ends, if you have superglue, you can use it to secure the strands in place (make sure not to use the superglue on sections of the paracord that will be seen, it should be used on the underside of the paracord).
Your Paracord Germ Grenade is now complete and hopefully you have created something similar to the one I tied. Add a carabiner to the bottom of the bottle or leave as it is, the end result is up to you.
