Easy ant farm! Uses Skippy peanut butter jars. I sealed the watering dish with a thin layer of silicone. The ants run up and down the connector tube all day by the dozen, fun to watch!! Super easy to print. Just cut the top of the plastic jars and put a .50" hole where a connector tube is required. Absolutely no post processing of any kind. You can see from the Youtube video that just how active the ants are in the connector tube, it's like a busy freeway all day. I have no idea why the ants are so active with this particular design.
