A floating fire ant raft is pushed down on the surface of water

A cluster of fire ants floating on the surface of water is pushed down with a pair of tweezers. Note the deflection of the water surface and how water does not penetrate the raft.




In the previous video a raft of fire ants floating on the surface of water was pushed down using a pair of tweezrs. In this video the ant raft is fully submerged and forms a ball like shape while retaining a pocket of air inside the ant cluster. The ants you see are underwater and the shimmery light around the cluster is the interface between water and air with the air being inside the ant cluster. This video shows how the ant ball is water proof.
