In Forge (you need 2 people for this) one person goes into the forge ball and spawns any ground vehicle and sets the respawn to never.

Then the other person drives it away and blows it up.

Then the first person makes another vehicle where the first one was and sets it so the minimum on map is also the maximum.

Then the second person drives it away and when the vehicle respawns the person in the forge ball picks this one up and the other one will float until the forge ball drops it.
