I feel obligated to add my silly mistake here. I was playing with SDR and was soldering together a small antenna for receiving ADS-B signals.

I soon realised my electric soldering iron wasn't powerful enough so I nipped out and bought a miniature blow torch. The kind which are basically a big cigarette lighter. Having got it home I tried igniting it a few times and nothing happened. I held it up to my ear to try to hear if there was any gas coming out, sure enough there was gas coming out, which in that instant ignited beautifully into a 700 degree flame pointed right at my ear.
