PVC Feeder Tube

Two foot long 4 inch diameter PVC pipe with caps on each end secured by bolts and with holes drilled at random in the sides. We give this to our Orangutans to encourage tool use and increase activity levels.

Two of our Orangutans (Tara and Sally) trying to extract peanut butter from the device.

This device was made from a two foot long PVC pipe with PVC caps held in place with bolts. Holes of varying diameter were then drilled into the pipe. We used a four inch diameter pipe but different diameters and length of pipe could be used. We used bolts to secure the ends so that they could be removed for easy cleaning.
