· Take 2 spoons, one slightly larger than the other. Place pill or rocks in larger spoon. Place bowl of smaller spoon on top and apply pressure, gently at first - press too hard and it'll splinter, spraying bits all over the place! As the pill/rocks break down, gradually increase the pressure to gain a finer powder.
