Why do mosquitoes bite only some people? Because they are lazy. No. There are a number of reasons why some people are more prone to mosquito bites. One of them is body odor. Millions of bacteria which live on our skin produce various gases. These gases form our body odor. Some of these body odors attract the mosquitoes. So, this is the reason why m... Read More

Key Insights

• 🅰️ Mosquitoes are attracted to body odor and certain blood types, making some people more prone to bites.
• 🥵 Hot air balloons float due to a change in density caused by heating the air inside.
• 🍵 Airplanes are designed to handle lightning strikes, with the outer skin made of conductive material to redirect the electric current.

Questions & Answers

Q: Why are some people more prone to mosquito bites?

Some people are more prone to mosquito bites due to factors such as body odor, blood type (Type O is preferred by mosquitoes), and increased carbon dioxide and substances in sweat produced during exercise.

Q: How do hot air balloons float?

Hot air balloons float because of a change in density. When the air inside the balloon is heated, it becomes less dense than the surrounding air, causing the balloon to rise.

Q: What happens if a plane is struck by lightning?

When a plane is struck by lightning, the electric current travels through the outer skin of the plane, which is made of aluminum, and exits through another extremity. This design protects the plane and passengers.

Q: Why can't we tickle ourselves?

We can't tickle ourselves because our brains are programmed to predict and recognize our own movements. There is no surprise or threat when we touch ourselves, which is necessary for the tickling sensation.

Summary & Key Takeaways

• Mosquitoes are attracted to body odor, with certain body odors being more appealing to them. Additionally, they are more likely to bite people with Type O blood and those who are exercising.

• Hot air balloons float due to a change in density. When the air inside the balloon is heated, it becomes less dense than the surrounding air, causing the balloon to rise.

• Airplanes are designed to handle lightning strikes. The outer skin of the plane, made of aluminum, allows the electric current from the lightning to pass through without harming the passengers.

• Our brains are programmed to predict and recognize our own movements, preventing us from being tickled by ourselves.
