This is a show, where the students sit together in the large auditorium. The teacher demonstrates a number of science experiments with smoke, flames, soap bubbles, liquid nitrogen and more. The teacher asks questions along the way, so the students have the opportunity to interact with the show. There will be big flames, loud bangs and lots of smoke from the smoke machine.
