Yes, but in our experiments - mine and Belly's - in order for the resonance frequency to affect the world around us, they would have to set in two or more locations. The resulting field would faze that area, effectively creating a soft spot through which we could send things to the other side.

But within a day to 36 hours depending on the size of the object, the worlds would require equilibrium and a thing of equal mass would need to be transported back to our world.

So long as the frequencies are only be tested in a singular location, it is unlikely to shatter any glass beyond that of the lab's direct location.
