So just for fun i had a little plastic container with some ants and like 3 blades of grass in it (I released all ants afterwards). I had about 15 ants in there. All of them we on the bottom scrambling or climbing the grass, none on the side of the contain. No ants but one. This one ant would constantly try to climb up the plastic but when he got to around the top he would fall. Then he'd do it again. He repeatedly did this falling down each time. Does anyone know? Its not a coincidence because he was the only ant doing it? It was the common black ant i used.
