Kurzgesagt – In a Nutshell - What If It Rains Bananas For A Day?
The video begins by addressing a viewer's question about powering Tokyo with jellyfish. Tokyo requires 280 terawatt hours of electricity annually, more than several countries combined. The idea of using jellyfish, specifically the Nomura jellyfish, is explored. Despite their size and abundance, the energy generated from their movements using piezoelectric materials is minimal, requiring 29 billion jellyfish to power Tokyo, which is impractical and environmentally damaging.
The second scenario considers the impact of banana rain instead of water. Calculations show that replacing daily global rainfall with bananas would result in 11.1 quadrillion bananas, causing catastrophic damage due to their weight and velocity upon impact. The aftermath would include infrastructure destruction, environmental damage, and a significant increase in methane emissions, leading to global warming and mass extinction. The video concludes by emphasizing the absurdity of these scenarios while encouraging viewers to continue submitting questions.
Key Points:
- Powering Tokyo with jellyfish is impractical; it would require 29 billion jellyfish and cause environmental harm.
- Piezoelectricity from jellyfish movements generates minimal energy, insufficient for large-scale power needs.
- Banana rain would result in 11.1 quadrillion bananas, causing massive destruction and environmental issues.
- The methane from rotting bananas would significantly increase global warming, leading to mass extinction.
- These scenarios highlight the absurdity and potential consequences of seemingly simple ideas.

3. 🍌 What If It Rained Bananas?
- If for one day every raindrop was replaced with a banana, the impact would be catastrophic due to the sheer volume. A storm could result in several million bananas falling on a single square meter, akin to a banana asteroid hitting Earth.
- The average global daily rainfall is 1.33 trillion tons of water. If replaced with bananas, this would yield 11.1 quadrillion bananas globally, weighing the same 1.33 trillion tons.
- The Sahara Desert alone would receive around 15 trillion bananas, providing enough calories to feed the world for over two months.
- Globally, the banana rain would provide 1.2 quintillion calories, enough to feed everyone on Earth for over a hundred years.
- A falling banana from 3000 meters would reach 240 meters per second, impacting the ground with the energy of a bowling ball dropped from 50 meters, causing significant damage.
- In London, this would equate to a storm of 21 billion bananas, or 2.5 million tons, destroying infrastructure and causing mass casualties.
- Globally, infrastructure and natural environments would be devastated, resulting in a thick layer of rotting banana mush, leading to severe ecological damage.
- The decomposition of bananas would release 160 billion tons of methane, 280 times current annual emissions, leading to a sudden and catastrophic spike in global temperatures.
- This increase in methane and temperature would lead to a mass extinction event due to the inability of ecosystems to cope with the rapid change.
