Straw Aquarium Bubble Tube

Use a drinking straw to provide your fish and other underwater creatures with a bubble playground! Fill one end of the straw with silly putty, cover the putty with tape and blow lightly into the straw to ensure the straw is air-tight. Use a needle to poke holes all over the straw and attach an air pump tube to the open end of the straw with silly putty and tape. Place several rocks on top of the tube to keep the bubble maker on the base of the tank or hang the tube along a wall of the aquarium with suction cups.
