exploring that old neon pump

Remember this old gem? As far as I know there are not any simulations of it actually pumping, a sound challenge. I wrote a full tutorial on how to build it last fall, but stop short of a sim. However I feel I am particularly qualified to get this to work because I have built pumps that almost pumped, and cnts filled with gas that eventually held together.


Here's a pick with the Ne pool. We'll see how it goes, as always, but the last few months have been crazy, and the next couple of weeks are downright bonkers, so stay tuned.
