[MCU/Marvel] If Antman throws a blue Pym Particle Disc at a trarget and misses, what happens when it impacts the ground?

I would guess that the discs have a mass threshold, and if they impact a sufficiently massive target, such as a building or the the ground the particles will simply disperse and be ineffective. 

A more powerful source than a handheld disc would be needed to effect an entire structure, as we have seen.
