  1. There is an easiest way to do this.

    First, Just cut the bottle like the video how he cut the bottle (skip the sandpaper step).
    Second, Just force to put the cap on the cutted side (not at the cap placer).
    Third, Just get another cap of that bottle and put it to the cap placer.

  2. That's genius will be trying this myself. Also seen a guy do a similar thing with straws where you heat the end and crimp with pliers and fill up with salt pepper, oil etc and crimp other end small lightweight and completely waterproof. Great idea prefer your idea as it can be used over and over again 👍🏻

  3. Saw something similar containing potassium permanganate in one side and glycerin in the other (they catch fire when mixed) Might be worth a try… though you'd need to make a thicker separator and I'm not sure the smoke it produces would be good to breathe.
