5. Rotten fish instead of night vision goggles
Many animals have perfect night vision. However, people aren’t so lucky and have resorted to inventing things like night vision goggles. What do you do if you don’t have a pair just lying around your house? You can find an alternative in nature. For example, miners in Newcastle, Great Britain, used rotting fish. The bacteria that feed on rotting fish gives out enough bio-luminescent light to help the miners see their way in the dark.
American miners found a more pleasant source of light and filled glass jars with lightening bugs. Also, you could try to find bio-luminescent mushrooms like the Indians in the seventeenth century did. Or like the Japanese, during World War II, who used shining clams in order to be able to read maps at night
6. Goldfish instead of a beer
Humans have looked for ways to make alcohol almost everywhere, and now they’ve found it in goldfish. It appears that alcohol helps fish to survive in extreme conditions. For example, when a lake freezes and all living organisms become deprived of oxygen — the goldfish learned to produce lactic acid to stay alive.
