DIY Aquarium Air Stone

Create an air stone for your aquarium tank! Find a pebble and push the stone firmly into the end of an air tube. Use a straight pin to poke holes all around the end of the tube and attach the opposite end of the tube to an air pump. Place a small rock on the tube to hold the bubble tube to the bottom of the tank or build a small volcano-shaped cave with a hole near the bottom for the tube to enter. Consider using aquarium silicone to glue the end of the tube in a circle or spiral for varying bubble effects.
