I watched a documentary how polar bears break into seal dens half rearing up and pushing down with their arms.
I imagined a polar bear exhibit where visitors can interact with the bears, observe bears strength and provide them with enrichment at the same time. There is a balanced metal beam, not unlike a children swing, going between bear and visitor areas. On the visitor side, it is weighted with, say, 200 kg. Visitors can press a button, which releases some dog pellets into a transparent tube located on top for the beam. The polar bear can press the beam on his side, lifting 200 kg and replicating the movement of breaking the ice above a seal den. Then the pellets roll down along the beam to his side, fall down, and the bear can eat them. There would be a similar device inside visitors area, where a family could check how many people are needed to press down 200 kg.
