The Pym Disc Launcher is a special weapon that shoots Pym Discs to the specific target effectively shrinking the person into a size of an ant.

It was used by Scott Lang to launch the prototype Pym Discs to shrink the money inside the bank but it resulted to continued shrinking until it's gone.

Then it was used by Hank Pym to launch a perfected Pym Disc to shrink Cassie Lang so Scott Lang could save her from Crossfire's grasp.
