This is an oversized electronic capacitor from the 1989 film "HONEY I SHRUNK THE KIDS" starring Rick Moranis. In the film, Wayne (Rick Moranis) develops a machine that can shrink things and inadvertently ends up shrinking his children, sending them on an adventure through their own backyard. The item appears to be made of resin.
