Here’s a chance to create your own automatic fishing machine inspired by Aboriginal engineering. Automatic fishing machines were, and may still be, used by Aboriginal people to catch fish in shallow waters. This activity is based on a fishing machine invented by Aboriginal engineers and used near the Murray River.

If you thought humans were the only fishers who use nets, think again! Humpback whales work together to net and herd fish, making the fish easier to eat. But these whale nets are made of bubbles! To learn more, it’s time to blow some bubble nets ourselves.
