  • It's AumSum Time

  • Hi guys.

  • Can you guess the title of my next video?

  • My horse fainted.

  • Somebody help.

  • Just kidding.

  • Hurry up.

  • Write your guess in the comments section below.

  • How does a spider make its web?

  • No.

  • On its underside, a spider has organs called spinnerets that spin silk threads.

  • First, it connects two end points like two branches with silk threads, forming a bridge.

  • It then releases a loose thread.

  • From its center, it adds a new thread, pulling it to form a Y shape.

  • It joins the 3 points to form a frame.

  • Then lays radial threads till the web becomes strong enough.

  • Finally, from the center, it spins spirally completing the web.

  • How do snowflakes form?

  • My snowman makes them.

  • You wish.

  • A snowflake begins to form when a supercooled water droplet in the sky.

  • Freezes onto a dust particle or pollen forming a tiny ice crystal.

  • However, when water freezes, its molecules arrange themselves in a hexagonal pattern.

  • Thus giving the crystal a hexagonal shape.

  • Now, as the ice crystal keeps falling, it comes in contact with more water.

  • As a result, the water starts freezing on the six corners of the ice crystal.

  • Causing branches to grow on the corners and thus, giving us a beautiful snowflake.

  • Also, as the atmospheric conditions are the same on all sides of the snowflake.

  • The branches grow identically.

  • Thus making the snowflake symmetrical.

  • But since every snowflake follows a different path to the ground.

  • It encounters different atmospheric conditions.

  • Hence, it is said that no two snowflakes are the same.

  • They all tend to be unique.

  • Topic: Human hair.

  • Why do we get white hair?

  • Because we cannot get blue hair.

  • No.

  • Our hair is basically made up of keratin, a colorless protein.

  • Hence, before our hair comes out of the skin, it is almost white.

  • How's that possible?

  • I had black hair during childhood.

  • Don't worry.

  • I'll explain.

  • Our hair grows from hair follicles.

  • A hair follicle contains melanocytes which produce melanin.

  • Melanin is injected in the keratin cells during the growth of our hair.

  • This melanin gives color to our hair.

  • Now, the color of our hair is dependent on the type of melanin injected.

  • Eumelanin makes our hair black or brown while pheomelanin makes our hair red or blond.

  • However, as we grow old, the melanocytes decrease the production of melanin.

  • Thus, less melanin is injected in hair, causing them to eventually turn white.

  • Topic: Ignition temperature.

  • Why is it easier to burn dry leaves but not green leaves?

  • Because it is easier to spell dry than green.

  • No.

  • It is because of ignition temperature.

  • Ignition temperature is the lowest temperature.

  • Which a combustible substance starts burning.

  • Now, green leaves have moisture or water in them.

  • So, can I use them as water balloons?

  • Please listen.

  • Water has a property of absorbing a huge amount of heat before evaporating.

  • Hence, when we try to burn green leaves.

  • A large amount of heat is required to first evaporate the water.

  • Then to reach the ignition temperature of leaves, thus not allowing the leaves to catch fire easily.

  • However, dry leaves don't have water in them.

  • Hence, they don't need much heat, making them burn easily.

  • Why do dead whales explode?

  • Because there are thousands of firecrackers in their bodies.

  • Stop bluffing.

  • When a dead whale accidentally gets washed up on a beach.

  • It begins to decompose as it is not eaten up by sharks or other fishes.

  • During decomposition, various gases like methane and carbon dioxide are produced within its body.

  • But since there is a thick layer of blubber under the skin of whales, the gases cannot escape out.

  • Thus, they begin to build up inside the whale's body, causing it to bloat.

  • Now such gases are also produced in other animals after their death.

  • But since the body of a whale is large.

  • It produces more gases, thus increasing the pressure in its body.

  • Eventually, due to the increased pressure, the accumulated gases, tissues, flesh, etc.

  • Forcefully come out through weak spots, thus creating an explosion.

  • Hence,

  • It is always advised to not stand.

  • Or sit on a dead whale because it might lead to increased pressure at weak spots.

  • Thus causing an explosion.
