For sand, my dad bought a huge bag of it, which has lasted me for ages. Actualy, it\'s almost run out now, after a project friend and I worked on. We needed to add the sand to this big urban gaming board, and basicly we would just spread glue on an area, and flood it with sand. once we finished, and the glue dried, we had no clue how the bugger we were going to get rid of all the sand without having to take a tedious amount of time. Luckily, during the summer it had been boiling hot, and my dad had also bought a huge powerful fan (it was so strong, even at low settin it blew books out of your hands). We set up the fan, turned it to full, and blasted the sand away in a massive wave. It was quite impressive.
Wow, I really didn\'t mean to write that much.
