This is the prototype.
A twig runs up the middle, the tube with the ants is screwed in, with another tube screwed in for water.
Feeding is done by putting the food on a small piece of foil, snagged at the top of the twig.
Raj put small holes in the top of the lid, but as I judged them not escape proof, I plugged another lid with cotton in a bigger hole in the middle before re-applying the inner lid.
This morning the ants were climbing the twig to get their food.
Let's see how they do!
