Algodoo

I have in the fully detroyable construction site. The light posts can be destroyed, aswell as barriers, pallets of bricks and cars.

They are?

I can't really tell how it behaves, because my laptop is extremely slow.

So?

Enter this into the "oncollide" section -

(e)=>{scene.addwater({vecs = [e.pos]})}

Then when you hit the object (preferable a circle) water should come from it.
