Kids can learn a lot of biology from just catching crickets in their front yard and observing their behavior. This cricket cage allows for keeping crickets on the desktop and is made out of empty 2-L bottles with a bed of white sand for a dollar. The plastic is clearer than a jar. After observing and studying the crickets the cricket can be released and bottle recycled. The glue left from the label on the bottles was removed using a petroleum product and the ink with rubbing alcohol.
