Algodoo

Very easy to use, simply load the shell, (pointy things on the right) into the tube (you can insert them upright so no need for fiddly fiddling) and watch the reaction. Thanks to Anatabo for the gunpowder.

I suspect it to be the first mortar using gunpowder on phun, but if m wrong don`t bite my head off.

enjoy

ps: it would be nice if somebody could make a nice little target and game out of this, thanks
