methanephone
An instrument for detecting methane in mine air. It contains an electric battery that sustains a small electric glow light. As soon as a certain percentage of methane enters the workings, a tiny explosion occurs in the fuse head, where a fine wire filament is melted and starts a bell ringing continuously.
