@Castel_Fan it can also escape thru glassand some other things depneding on thickness
looks kinda similar to something i made
i dont know every thiing in tpt
also the hole in the glass isn't needed even without pump cuz INSL doesn't contain pressure so pressure escapes from there
the hole is for pressure to come out
why is there a hole in the glass?
ngl tung sould glow more like its dim
