DIY Air Pump Humidifier

Use an air pump to increase the humidity for your hermit crab or reptile! Drill two holes in the lid of a plastic container. Thread an air hose into one hole, attach an air stone on the end of the hose and attach the other end of the hose to the air pump. Thread a second air hose in the other hole and feed the end of the hose into your terrarium. Adjust the hoses so that the air stone is nearly at the bottom of the container and the terrarium hose is just inside the lid, and glue the hoses in place. Partially fill the container with water and turn on the air pump.
