- Get 2 clean, glass jars to start off with (One Large and one small enough to fit inside).
Put the smaller jar upside down in the bigger jar in the middle (a little glue will help this stay) this is to make sure the ants tunnel on the outside of the jar and not in the middle.
- Fill your jar up 1/3 of the way with soil. (Don't pack it too tightly or the ants wont be able to dig tunnels)
Find a nearby colony of BLACK ants. You'll probably be able to find one in your backyard.
Make sure that you have your gloves on. Take a scoopful of the ant colony and dump it in your jar. Make sure that you don't get too big of a scoop, because then the jar will overfill (if it's a small jar) with dirt and ants!
Try to find the queen ant. The queen ant is the largest ant of them all, and she'll have three extra eyes in between her normal two. If you can't find her, don't worry, your ants will still make their home in the jar. Having the queen ant will just help your population of ants stay steady for a while.
Close the top of the jar. Wait a few days and the ants will start to build their tunnels around the jar walls.
Open the jar cap a few times a week to let some fresh air in. You can put your ants in the fridge for a few minutes before you open up the jar. This will make them slow down so that the chance of them escaping is smaller.
