Why don't Birds get Electrocuted on Power Cables? + more videos | #aumsum #kids #education #children

TL;DR

Electricity flows through power cables due to least resistance. Vultures have strong stomach acid for protection. Dry ice can cause severe frostbite. Birds need gravity to swallow food.

It's AumSum Time. Why don't birds get electrocuted on power cables? Because they wear shock proof shoes. No. Electricity is the flow of electrons through conductors. It always takes the easiest route. That is, electricity always flows through a path of least resistance. Now, power cables through which electricity flows are made of copper. Copper of... Read More

Key Insights

• 💐 Electricity flows through least resistance paths like copper cables.
• ✊ Birds' resistance prevents electrocution on power cables.
• 💪 Vultures' strong stomach acid protects them from harmful microbes.
• 😘 Dry ice's low temperature can cause severe frostbite.
• 🥶 Storing dry ice in airtight containers can lead to dangerous pressure buildup.
• 🐦‍⬛ Birds utilize gravity to swallow food due to lack of peristalsis in their esophagus.
• 😋 Understanding vultures' stomach acid helps prevent food poisoning.

Questions & Answers

Q: Why do birds not get electrocuted on power cables?

Birds do not get electrocuted on power cables because their bodies offer greater resistance compared to copper power cables, which have the least resistance, causing electricity to flow through cables instead of through the birds.

Q: How do vultures avoid food poisoning from decaying flesh?

Vultures have strong stomach acid that can corrode metals, which destroys harmful microbes in decaying flesh, thus protecting them from food poisoning.

Q: Why is dry ice considered dangerous?

Dry ice is dangerous due to its very low temperature causing severe frostbite upon skin contact and the potential for explosions if stored in airtight containers, as it sublimates from solid to gas.

Q: Why do birds need gravity to swallow food?

Birds rely on gravity to swallow food as their esophagus does not have muscular peristaltic movements, so tilting their heads up helps the food slide into the crop pouch through gravitational force.

Summary & Key Takeaways

• Electricity flows through power cables as they offer the least resistance, while bird bodies offer greater resistance.

• Vultures avoid food poisoning due to their strong stomach acid that kills harmful microbes.

• Dry ice is dangerous due to its extremely low temperature causing frostbite, and can lead to explosions if stored in airtight containers.
