Please choose the correct ending to complete the given sentence: Pets and Animals: [header] How to build an ant farm [title] Get two glass jars with lids. [step] You'll need a large jar and a smaller one that just fits inside. The dirt and ants will be placed in the space between the small jar and the large jar.

Ending1: Pick a smaller jar for the ants to burrow in. [substeps] If you'd rather have some people dress up as ants, simply place the large jar directly on top of the smaller jar with the lids facing the ants. Ending2: The small jar functions as a way to take up space in the middle so that the ant colony will build tunnels and lay eggs close to the outer edge, putting these processes in plain view. Skipping this step will allow the ants to burrow deep toward the middle of the jar, which they'll naturally want to do. Ending3: [substeps] The larger jar will be used for watering the ants and the smaller jar will be used for coating the ants and gathering food from insects. These two jars make great ant farm equipment in a lot of space and can be used to build many ant farms at one time. Ending4: [substeps] Since ant mounds have tiny holes built up between lids that make it easy to dig into the dirt, set the front jars aside for the next steps. [title] Make and use the newly formed ant mounds.
