From Beyond

One time in junior high, we put together two cans connected with a string to show that we could communicate over long distances. We didn't get a good grade on it, since that's probably something more suited for a 2nd grade class to do, but we were in a pinch, and what can we say... we were pretty stupid back then (you might say not much has changed). We always thought it would be pretty cool to communicate with another dimension, but there's no way that we would could have done it with just some shitty string and a couple of tin cans. What we needed was a dimensional resonator! At least that's what they had in 1986's From Beyond. Stuart Gordon directs the film, an adaptation of a short story by H.P. Lovecraft.
