Ants craft tiny sponges to dip into honey and carry it home

The ants experimented with the tools and eventually showed preference for certain tools – even unfamiliar ones. The ants would drop the tool into the liquid, pick it up and then carry it to the workers back in the nest to drink from.

Senilis started off using all the tools equally, but then focused on pieces of paper and sponge, which could soak up most of the diluted honey they were offered. This indicates that they can learn as they go along.
