In runescape how do you set up more then 1 dwarf cannon?

Question

i no it can be done cuz i saw a guy set 2 cannons up at fire them both and they were both his cuz no one was around besides me and then i asked him he said it a secret or somthin

Answer 1

No you can't do it. Someone could have just been out of your screen or something it can't be done. He must have hacked or something.

Answer 2

sorry but there is no way to do that, you can only set up one at a time.
