Gir- The tubes come with a Kricket Keeper which you can get at most pet stores.It's a place to keep live crickets, and the tubes are angled down into it. They naturally climb up into them to hide, then you just pull out the tube, cap it with a cap of calcium, shake it up and voila! Shake & Bake Crickets!
Hehe, Dana does that too Jolyn! She gets all excited just at the sight of the tube, all hyper and puppy likeIt's so adorable!
