John Stockwell, Fisher Stevens and Dennis Hopper appear in this low-budget sci-fi/comedy from 1985, MY SCIENCE PROJECT, where teens find an alien contraption of seemingly unlimited power that opens a portal from which people and things from Earth's past and future pour into their high school.  Now the teens need to pull the plug on it before everyone is in mortal danger.  It's a very 80s movie in the best ways -- and the worst.
