How to make a click bomb?

So this guy was using tool gun on this sandbox server and when he clicked it would make a huge bomb where he clicked.
The sandbox server has the addons
J.I Defence Solutions

If anyone knows how to make this please tell me.

Likely advanced duplication was used. Just create a bomb of sorts in the air, attach a ranger on the bottom of the prop and wire some form of ignition. Copy it and set the spawn height to were the ranger will trigger.
