About the sample
This chemical element is a commercial sample. Argon is packed in a glass ampoule under low pressure. There is a mini Tesla coil next to it. By switching on the electric circuit, the coil generates a field with a high voltage & frequency which makes this gas glow. The push-button switch is located on the right side of the frame of the display.
To see the noble gas glow, push the button and the coils will be active for about 30 seconds. After that, the Tesla coils will be disabled for about 5-6 min in order to protect them from overheating. This sample is a part of the private collection of Metodija Najdoski.
