Brief description: A variety of soft, sticky treats can be placed in the bottom of each bucket, which is then hung to the outside of the caging. The chimpanzees are provided with tools (such as bamboo sticks or long plastic straws) to fish out the treats.
Materials: 5 gallon bucket, chain, bolts, washers, lock nuts, and firehose if desired to cover the chain.
Tools needed to create the device: ratchet wrench, socket wrench, hole saw
Assembly instructions: Cut several holes in the outside of each bucket using a hole saw. Remove handles from the buckets. Cut chain to desired length. If desired, add firehose to cover chain at this point. Add a washer to a hex bolt, then insert hex bolt through one end of the chain and through one of the holes in the bucket from the removed handles. It is ideal to use bolts that are short enough that they do not enter the interior of the bucket itself to allow for stacking of the buckets and requiring less storage space. Apply a locking nut to the end of the hex bolt and tighten. Repeat this process for the other side of the bucket.
How to use: Apply about 1/4 cup of soft, sticky treats (mashed bananas, pudding, mashed potatoes, etc.) to the bottom center of each bucket. Attach each bucket to the outside of the caging, and provide the chimpanzees with tools.
Price: ~$8 per fishing bucket
