Once again, Ron (YouTube channel Glasslinger) is making glowy stuff from scratch. In this video he makes the largest neon numeric display that I've ever seen. Yes, even bigger than Dalibor's latest design.
The tube isn't perfect but then it is hand made from scratch, all glass work done freehand. Really quite impressive! Excellent demonstration and explanation of the process of pumping, degassing, testing, filling, etc.
Trigger Warning - The guy making the tube has pink hair and cross-dresses in women's clothing, so if that sort of thing upsets you don't click!
