An airstone can be made from a grinding wheel. Sit the wheel on a tin lid (for example off a coffee can) & make a bung with a pipe to fit in the central hole. Tie the lid on the back of the wheel with wire. Try it in a bucket of water. I didn't bother doing this as I got a huge airstone from the Aquarium shop.
