Found myself with two things this past weekend: spare time and spare 550 Paracord.
So I took a plastic water bottle with the sport cap, popped the middle piece out and had a perfect container.
I know I should use floating rope (Paracord will sink once it gets saturated) but I had 50' of hi-viz yellow cord so I figured why not use that.
Actually, I'm thinking of throw bags in relation to kayaking. No helmets unless you are white water paddling.

And THAT is how I found myself doing this LOL. I watched a video where someone made it and my first thought was "okay, but I don't see why". Then I found myself thinking about it and what I'd change. Next thing you know, I am posting here about it.
And now you are too! 😀
I do think I'll keep the plastic bottle. As @hikermor said, the plastic bottle itself doesn't really have any mass and it's more of a simple container and holder of the wax (which gives it the little bit of extra weight to assist in throwing further). And, if I am trying to assist a complete &%*#^ then I can always claim that hitting him in the head with the bottle was a total accident. 🤣 🤣 🤣
But that said, now I am wondering if there's a relatively easy way to hollow out a pool noodle more than that 1" diameter hole. That would add enough mass to assist in throwing further, has the benefit of floating and can be in a bright color to make it easier to see, and if you do hit someone with it (I swear, by accident) then it's no big deal. Maybe a 14" section and a razor blade/boxcutter - slice it in half vertically, carve out a larger space inside, and then 4 or 5 zip ties to put the two halves together again?
