Methane Bubbles take 2

To the (actually fairly genuine) gasps from a captive, and mildly captivated audience, Mr Bell attempts methane bubbles the dangerous way.

Rumours that Mr Bell set off the school fire alarms during this demonstration are greatly exaggerated.

Rumours that Mr Bell scorched off some hair on his right arm during the demonstration are unfortunately rather less exaggerated.
