Packing list: 5 rare gas tubes (including: helium, neon, argon, krypton, xenon) Note： The packaging only contains gas tubes and does not include activation devices. Please purchase activation equipment such as Tesla coils, ion spheres, and electric spark leak detectors separately.

• Package includes: 5pcs inert gas tubes (He, Ne, Ar, Kr, Xe), excluding excitation device.
• The dimensions of the high borosilicate glass shell are approximately 20 * 100mm. The internal filling gas has a purity of up to 99.999%.
• Glass sealed gases themselves are colorless and transparent, they are not empty, and they need to be under high voltage electric field conditions to emit light.
• You can use ion luminescent balls, Tesla coils, or electric spark leak detectors to make it glow. When the sealed gas approaches the high-pressure arc, the gas will emit light.
• Different gas elements emit different types of light, which is very beautiful and suitable for element collection, hobbies, teaching exhibitions, gift, etc.
