Step Four: Add the Styrofoam
You can rip up Styrofoam plates or cups and add them into the acetone or gasoline.
Keep in mind that it must be pure Styrofoam in order for this survival fire putty trick to work. In other words, if the item you rip up does not work, that means you need to select a different Styrofoam item to rip up.
Step Five: Form the Styrofoam
It will be necessary to put several pieces of torn up Styrofoam into the bottom of the bottle, and you may need to put a bit more acetone or gasoline on top of it.
You need to push the Styrofoam down to make it all fit and to shape it.
You can use a pencil or a twig to help you accomplish this part of the process.
The yellow in the image came from the pencil.
