Step 3Fill Tube

Fill Tube
Depending on your filling requirements, you may wish to leave the tube as is or you may wish to modify it. I chose to modify it so that it would act as a shower head to ensure maximum coverage.

To do this, I simply drilled a bunch of holes through the tube and crimped the end. Drill enough holes to eliminate pressure build up and to cover the desired area inside the bottle.

To crimp the end, simply heat the end 1/2 inch or so, without burning it, and pinch shut with a pair of pliers and hold. If it doesn't seal shut, heat it a little more and try again. Heat slowly to prevent discoloration, but enough to liquify the vinyl. If you use another material, terminate accordingly.
