Great gadget! Well constructed display.
For Nobel Gas Glass Tube Kit (including 10 tubes)
I bought this as a present for my son who is a scientist. I love the concept of this device. I was concerned about the shipping since this contained small glass vials, but it was packed really well and arrived in perfect shape. The different gasses produce really nice glowing plasma. If you have a diffraction grating you can see the emission lines really well. My son was thrilled with this and displays it for friends when they come over. Thanks for a great product.
