Parents are always concerned that their children will grow up and reach their full potential. But how does one discover what direction to push little Johnny or Sally? If you ask the child what they want to be when they grow up, they will invariably answer something unrealistic like “Astronaut” or “Ballerina.” If parents followed their child’s desires, we would have a surfeit of people whizzing through space or dancing on point or both, and no rodeo clowns or hod carriers.  Fortunately, this device takes the guess work out of a child’s path by revealing their true potential. Plus, if the child fusses at being told that, instead of being a famous explorer they will have a fulfilling life as a parts manager for a ball-bearing company, the device delivers a powerful shock until they accept what the device has revealed as their true calling.
