Pop balloons with your harpoon

And the Eskimo community basically camps out on the edge of the ice here, waits for a whale to come close enough to attack. And when it does, it throws a harpoon at it, and then hauls the whale up under the ice, and cuts it up.

Whales cannot be humanely killed they are too large, and even with an explosive harpoon, it is difficult to hit the whale in the right spot. Moreover, whalers do not want to use a large amount of explosive, because that would blow the whale to pieces, while the whole point is to recover valuable oil or flesh.
