Pop a top and catch a fish while you’re on the water.
If you need an emergency fishing hook, just grab a soda can. Cut an opening in the bottom hole in the tab. Make sure that you cut in at a slant. Then start cutting away as much metal as you can around the hook. File the hook into a sharp point. It won’t quite be the same as fishing in ocean off of Costa Rica, but it will catch you a good meal.
