When I plugged my assemblage in, there was a great buzzing, the electromagnet in the core of the thing whirled madly, and the lights in the house began to pulsate. The whole thing whined and fluttered. There were showers of sparks. Parental cries of alarm rose from downstairs. As the machine destroyed itself the pulsation of the house lights became a dimming, until the bulbs glowed orange-red. Then they burst to blazing life, a good number of them blowing out in the process.
