A bit of research can do you good

"How do they work?
A crackle tube works similarly to a Luminglas device. The beads, coatings,
the gases, and the power supply are the same. The shape is the only thing
that is different. Virtually any blown glass shape can be made to light up
as long as it can withstand being put under vacuum. (This is an important
safety concern: Never put a glass shape under vacuum unless you know what
you're doing! Implosions can easily happen and are extremely dangerous!)
Large crackle tubes (2" or larger) are made with double walls. This cuts
down the weight and forces the discharge near the outer glass wall. Double
walled vessels of this type require careful designing to prevent the glass
from cracking due to strains in the glass between the inside and outside
walls."
