Tech or Treat
About
The Tech Interactive turns Halloween into a day of trick-or-treat stations around the museum plus hands-on activities such as building a skeleton linkage and making Halloween slime or static-electricity ghosts. It runs Saturday, October 31, 10 AM–5 PM, at 201 South Market Street, San José, about a mile from San José Diridon Caltrain. It is included with general admission ($38 adults, $28 child/senior/student), and the Halloween laser shows in the Dome Theater are an extra ticket. Those laser shows ($16/$12) are on our calendar, as is Chabot Space & Science Center's Spooky Science family day on the same Saturday.
