I have an AntWorks Ant Farm
(http://www.fascinations.com/unique-toys-gifts/antworks.htm).  I would
like to build my own larger version but have been unable to find out
how the gel is made.  I am looking to find either the formula (and
instructions on how to make the gel) or find their supplier so I could
buy a quantity of gel (or the mix for it) directly to make a larger
ant farm.  I found a few sites that mention it is an Agar gel but with
anti-fungal and and-bacterial properties added to it.
