Enrichment

Orangutans, being the intelligent creatures that they are, get bored very easilly. As with most animals, prolonged periods of boredom will cause them to develop neurotic behaviour. As such, we give them many forms of enrichment, activities to keep them mentally and physically stimulated. For example, their keepers threw in a gani sack here, with sunflower seeds inside.
The orangs seem to love playing with the gani sack like a toy, using it as a cape, a burrow or even something to hang from (until it tears under their weight)
So here... throw in a gani sack, and see what they'll do....
