Bo Foster HELL OF SAND click here

I think this site was pretty interesting because you could make different cool designs and while your at it you could lay down some gun powder leading to C-4 and click fire and light the gun powder and watch the gun powder lead to the C-4 and watch it explode it was pretty cool. You could also make a spout and watch it fill up and or mix with the other colors of sand. You could also make a cool design and watch it fill up with the different color sands. I would refer this to another class mate if they have a creative mind.
