These series of outworlds or outside worlds feature clean, clear glass on the front and back, the side panels allow for connectivity and compatibility with our formicaria, the design is slim and features double lips on all edges, making escaping hard, especially when combined with an escape barrier, you can easily connect them and create your network of foraging areas, nests and tubing paths.
 
The top features dual lids with a removable plastic fine grid (0.3mm pores) and horizontal flat ledges to force the ants to walk upside down on a slippery barrier. You can quickly remove the mesh while preserving the ledge and depositing or removing food.
 
The mesh on the lid and side walls allows for plenty of air exchange in the foraging area; keeping humidity as low as possible creates a dry area that is key to preventing ants from digging or attempting to nest there. A key difference in this design compared to the "Glass display arenas" is the cross ventilation capability due to the mesh on the plastic side walls.
 
It is recommended to use a thick escape barrier (similar to "petroleum jelly") on all contact areas of the top lid to ensure a perfect seal and lubricate the parts. Also, use your preferred escape barrier method like jelly, oil or fluon on the top edge of each inside wall and the internal flat surface of the lid and around the mesh on each side wall.

Tubing size: 
 
The outside world has four opening holes for vinyl tubing, two on each side, the location of the openings matches most of our formicarium designs for ease of use; options for tubing diameter are 9.5 mm (3/8") or 12.7 mm (1/2").
 
Length/Dimension options: 
 
It is 8 centimetres tall by 10 centimetres depth, and we have two length options; 12 and 16 centimetres.
 
For a tubs and tubes set-up, the 12 cm option can accommodate a 125 mm length test tube diagonally; the 16 cm option can fit test tubes as long as 150 mm. 
 
Substrate:
 
Graded and uniformly screened for medium-small granules, thoroughly washed to remove fine dust "sandy" particles and dirt, oven-baked at 120 °C to kill mould spores and bacteria. Non-toxic and inert. This substrate is easy to clean and rearrange, and has a beautiful texture and look; it is safe for ants to bring inside the formicarium if they need to customize their chambers. This substrate does not absorb or retain humidity, helping ensure the outworld is as dry as possible to prevent ants from nesting or digging there.
