It is very easy to make an incubator for ants, for this you will need a 16x150 test tube, some clean water and cotton wool.
For the convenience of storing the incubator and observing the ants, you can make a tripod from improvised materials with your own hands, for this you can use insulation for water pipes, clips for fastening pipes, a DIN rail or a spatula for a frying pan.
