Pyrophones are organs where the notes are sounded via explosions or other forms of combustion. Often beautiful just to look at, they also make otherwordly noises (open up all these links at once for a real wake-up). Unlike other fire-based instruments, they can even play recognizeable melodies. Here's how to make one. They've become quite popular at events (7 MB video, more videos) like Burning Man, but they've been around since the 17-1800's. If you're new to experimental instruments, a read/listen through Gravikords, Whirlies and Pyrophones should be your next stop. Related: chemical harmonica, burning harmonica, singing tubes.

"On March 18 [1937] students prepared for the next day's Inter-scholastic Meet in Henderson. At the gymnasium, the PTA met. At 3:05 P.M. Lemmie R. Butler, instructor of manual training, turned on a sanding machine in an area which, unknown to him, was filled with a mixture of gas and air. The switch ignited the mixture and carried the flame into a nearly closed space beneath the building, 253 feet long and fifty-six feet wide. Immediately the building seemed to lift in the air and then smashed to the ground. Walls collapsed. The roof fell in and buried its victims in a mass of brick, steel, and concrete debris. The explosion was heard four miles away, and it hurled a two-ton concrete slab 200 feet away, where it crushed a 1936 Chevrolet. Of the 500 students and forty teachers in the building, approximately 298 died. Some rescuers, students, and teachers needed psychiatric attention, and only about 130 students escaped serious injury. -- From the Handbook of Texas Online. (Other accounts, personal recollections, and photos .)

It was one of the worst disasters in Texas history. With Texans' love of superlatives, why is this a story no one tells? [more...]
