Get a gravity lift, a dumpster, weapon holder invisibility orb and an open box.

Put the gravity lift on the weapon holder, then put the open box so you can fit the dumpster in between the gravity lift and the box.

Than put the orb in the box as close to the side that has the dumpster as you can.

Than delete the open box.

Get into the human again and go pick up the invisibility orb.
