ant farms

Are family got an ant farm about a month and a half ago. It didn't come with ants though. This past Saturday, we finally got the ants in the mail. It was during Michaela's birthday. We put the ants in the refrigerator for 15 minutes so the ants would not move around while we put them in the ant farm. It has now been 2 days and it is neat how they are making tunnels. We fed them a little piece of apple and gave them a few drops of water. It will be interesting to watch. If anyone knows anything about ant farms let me and my family know.
