SAN DIEGO, Aug. 15 (UPI) -- The San Diego Zoo shared video of its latest enrichment tool for orangutans -- a bubble machine.
The zoo posted a video to Facebook Friday showing the orangutans reacting with surprise and curiosity to the bubbles that begin to fill their habitat.
The orangutans seem initially wary of the bubbles, but soon start to pop them and try to catch them in their mouths.
"Who doesn't love bubbles?!" the zoo's post asks.
