a small test tube with a tightly seeled lid with 2 electrodes spaced closely together. i put 12 volts at a high current and watched it fizz up. the first time i tried this it exploded and the water and gas went everywhere.
Enjoy :D
Here's myself shooting my father's Norinco SKS. I put on the synthetic stock and scope on for him because it required a little finesse to cox the parts on. The reason why some wood remains on the gas tube is because the pin that helps hold the hand guard on is pretty much welded onto the gas tube.

A short video with a demonstration of my homemade vacuum tube. I made the tube several years ago, when I first started experimenting with ionized gases and tubes. This little PLASTIC tube has survived a power of over 900 Watts without any damage (while holding a vacuum)!

Love it. Just dropped Yugo SKS into a tapco stock. Not much gunsmithing needed at all. This tapco stock makes it really fun to shoot. have a bushnel redicle on the gas tube. its pretty dead on out to 200 yards with the redicle. "suprising"

A syphon is a continuous tube that allows liquid to drain from a reservoir through an intermediate point that is higher than the reservoir, the flow being driven only by the difference in hydrostatic pressure without any need for pumping. It is necessary that the final end of the tube be lower than the liquid surface in the reservoir.
