My previous bottle bulb was a failure of the good kind. I learned quite a bit so check it out first before proceeding.
This one is simpler to assemble, display and has greater reliability.
Extensive research along with clues from other Instructables members has lead me here...
Please play safe when using compressed gas, deep vacuum in glass vessels and electricity....
Step 1: Materials
Again you will need a clean glass bottle. I chose a clear bottle but a colored one would be preferable
A rough service light bulb.
2 part epoxy
some brass welding rod
A refrigeration schrader valve and stem.
a small section of 1 inch nylon rod.
Light wiring, heat shrink tubing and chain.
You will also need a vacuum pump. not a vacuum cleaner
Argon and regulator
