I've been pretty disappointed by the lack of Nostr content focused on moving liquids from one container to another, so let's talk about "jiggle siphons". The name says it all, a jiggle siphon (aka safety siphon) is a magnificently simple invention that lets you get a siphon started by just jiggling it up and down a few times in the container you're trying to extract liquid from.

It's a simple check valve (a glass marble inside the valve does all the work), so as it moves up and down in the container, it forces a little liquid into the tube each time, until there's enough to get a siphon flowing. If you've ever sucked gas or aquarium water into your mouth trying to start a siphon that way, you'll understand the value of this.

I've got a couple of copper ones I use for gas and diesel (it's much easier to get fuel out of a full gas can using this siphon than to try to dump it out with the crappy nozzle on the can), but if you just need one for water, you can 3D print one out of plastic and steal a marble from a little kid.

Here are the CAD files I used to make mine. You can use OpenSCAD to customize it to fit whatever size tubing and marble you have.
