How do I "prop spawn" a not prop?

[DPyro]

My friend and I were messing about on a construct map with water. He built a submarine and I built a destroyer. To properly whoop his rear, I need to make a depth charge launcher. I made a depth charge with a 2-5 second timer that starts when it hits the water out of a wired explosive and gates, but I don't know of any way to automatically create the depth charge when I press a button. Any ideas?

Advanced duplicator can create "pasters" that does this. But many servers block it, so you probably need to host your own.

With the Adv. dupe. Pressing reload with adv. dupe STool will create a prop spawner of your currently loaded dupe. Just position the end of the beam where you want the charge to spawn.
