If a 4D object temporarily intersected our 3-dimensional world, theoretically we would see only the 3D intersection, and it would change its shape as it passes by. What would happen if you grab this 3D intersection as it passes through our world, and not let go of it as it vanishes away?

According to the mass-energy equivalence, whenever energy is added to a system, the system gains mass. But hum.. "where" is this new mass located? And what kind of mass is it, it's like some subatomic particles that just came to existence?
