glass Tube:

What a cool glow tube.


For better fun we used a magnet to fix the tube,His effect is much better than he imagined.My classmates really like the feeling of it sucking.



Very cool project, I like the look of it in the glass tube!
What font did you use for the numbers, it's a nice clean look? And how far into the acrylic did you need to etch to get a nice visible glow?
