Jungle Rock

[Antenociti]

Am pretty sure, these have been carved - as has been stated, the stuff looks more like big piles of dung when just sprayed from the can.

But the material is probably MUCH easier to carve/cut than styropor (the materal made from millions of small pieces somehow pressed together, and making a horible mess if cut with anything but a hot wire cutter (which, in turn, produces toxic fumes...    )

Hopefully a helpful disambiguation of the different types of foam out there:  http://www.antenocitisworkshop.com/gbu0-display/foams.html

Actually PU foam is polyurethane and the isocyanate used to make it is the problem.

Well, these rocks certainly don't look like piles of dung. Lovely work, veryt effective and certainly lighter than the real ones I've used

Nice guide. 'Styropor' seems to be the trademark of BASF for expandable polystyrene - but the word is used (along with 'flamingo') for the material, regardless of manufactor, here in DK.
