I spotted this on Creative Review. Artist Benjamin Verdonck built a nest from tree branches, glue, foam, sand and a bucket of spit(?) and perched it on the side of this office tower in Rotterdam. He’s lived in the nest for 7 days. Check out the below video to see his antics and how the public reacted.

Yep, spit. Swallows use spit and regurgitated food to build their nests.
