Now then....
There used to be a cylinder of hydrogen here, but no longer. We only have hydrogen as a small percentage in an inert gas now, which is deliberately non combustible. But there might be some somewhere.

Thing is, if I was going to do this, I'd want to make a show of it. So I'd have to hunt round the lab for suitable chemicals to colour the flame.

I'm sure I had some strontium compounds somewhere...

Manchester airport's a local airport if you live near it...

But facetiousness aside, that's quite something.
