A character is testing out a device or performing an experiment in an area designated for testing purposes or just a field far away from civilization. Still, something will go horribly wrong in the process, or even horribly right, and nothing guarantees disaster will not occur beyond the testing environment. Typically involves a Mad Scientist, and the nearby locals who dread anything that happens. See also Disastrous Demonstration. Failsafe Failure may occur in this. May overlap with Training Montage and How Do I Shot Web?.
