Among the 30-plus attractions at the fair will include robot demonstrations, a place to make glow-in-the-dark jewelry, a night sky display at the ExploraDome, and an opportunity for kids to “make” their own earthquakes.

There will also be demonstrations of air pressure on a 55-gallon steel drum, and plenty of explosions and flames.
