Presenters will demonstrate the difference between physical and chemical change as they release a genie from a bottle, spew columns of foam with the use of a catalyst, turn water into juice, cause combustion to occur with no flame, and more.

Admission is $6 per person, $5.50 per person for groups of four or more; children younger than 18 months, free.
