Noble Rare Luminous Gases Element Collection, 99.999% Purity, Including Helium, Neon, Argon, Krypton, Xenon, Nitrogen, Oxygen, Carbon Dioxide, Air, for Collection, Display, Teaching, Gift, Pack of 9

I purchased these as a reference for what color is emitted by these gases. They were packaged well in bubble wrap and double boxed. I appreciate the care taken to package them. All tubes work. I found some gases need a fairly high level of energy from a small tesla coil to excite the gas to illuminate. As well as a dark room to see it, but i think that is expected.

Not as bright as in images I do have to say.

Very cool! My son introduced the whole family to his love for science.

These came quickly, wrapped very well in bubble-wrap. They glow nicely when used with our mini Tesla coils.

Got it as a gift for someone, so I can't really comment much beyond it appears to be your basic test tubes with noble gas sealed inside. The customer service is really communicative. The items were packed with extreme care- a box within a box, and bubble wrapped individually, as well as the sides of the 2nd box. They're nicely sized and would store perfectly on a test tube rack.

Really disappointed with my gas tubes. Only (4) illuminate out of 9. There is no returns. The items were carefully packaged so it doesn’t seem to be a shipping issue at all. It’s a manufactured problem.I have a green light in the room that is showing shining on glass tubes.

These work great with my Tesla coil. The noble gases have a higher luminosity than the Air, CO2, O2, and N2 but all of them illuminate and my students loved seeing them.
