fire ants are scooped into a new home

Fire ants float on the surface of water inside a bucket and are subsequently scooped into a clear plastic bin where they will be kept in a lab. Notice how the ants hang off the edge of the ladle used to scoop them up. Visit www.antlab.gatech.edu for more information and be sure to check out my other uploaded videos

A group of floating fire ants

This video shows a close up of the fire-ant/water interface. Note how the bottom layer of ants remains ON the water’s surface and water is prevented from penetrating the raft. Visit www.antlab.gatech.edu for more information and be sure to check out my other uploaded videos

about 3000 fire ants spreading out on water forming a raft (side view)

Video is sped up approximately 10 times. Approximately 3000 fire ants originally shaped into a ball are placed on the surface water. They spread themselves out into a pancake shaped raft floating on the water. The raft is waterproof due to the tightly knit “weave” of the ants in the bottom layer which serves as a platform for the rest of the ants to walk freely on.

8000 fire ants spreading on water forming a raft (top view)

Video is sped up approximately 15 times. Approximately 8000 fire ants originally shaped into a ball are placed on the surface water. They spread themselves out into a pancake shaped raft floating on the water. The raft is waterproof due to the tightly knit “weave” of the ants in the bottom layer which serves as a platform for the rest of the ants to walk freely on.

a fire ant ball is pushed underwater part 1

A continuation of another video I uploaded. 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. Visit www.antlab.gatech.edu for more information and be sure to check out my other uploaded videos

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. Visit www.antlab.gatech.edu for more information and be sure to check out my other uploaded videos
