Thats a cool idea and fair play to you for being innovative.

Unfortunately those gel products are a nuisance due to the fact that they absorb water through the process of gelatinisation and thus could turn into a sludge which is unpleasant to have to clean up. Basically it turns to a goo and mixes with the substrate.

Pathogenic bacteria can also thrive within it as it is a suitable medium for bacterial growth becuase of the water and starch.

Some owners have made their tarantula make a nest near the side of the cage.

Another option would be an Exo-Terra Reptile Den; http://www.exo-terra.com/en/products/reptile_den.php

That reptile den might be too expensive to have in many tarantula enclosures.

You also have to understand that tarantulas dont want to be seen and so they prefer a dark area. Its in their nature to hide away. What sort of tarantula do you want to test this on?
