it is a gel shit that the ants eat and they make tunnels and start a colony. and when ants die in the tunnels you have to get rid of the dead body because they can start ant desieses and kill the others. so no word of a lie the other ants carry the dead one to the surface so all you have to do is take the lid off and get it out. it is amazing watchin the tunnels develop and watch the ants work together to link them all up. and its pretty cheap aswell.
