  • Can you guess the title of my next video?

  • Hurry up.

  • Write your guess in the comments section below.

  • What is diabetes?

  • A rare diamond!!

  • Nooo!!

  • Diabetes is a disease in which glucose or sugar levels in our blood remain high.

  • Is it higher than the Statue of Liberty??

  • Naahhh!!

  • Most of our food is converted into glucose and released into the bloodstream.

  • Then, our pancreas makes insulin.

  • Insulin helps glucose get into the cells.

  • However, in some people, the insulin production is inadequate or it is not used well.

  • Hence, glucose stays and builds up in the blood, increasing the blood glucose level and thus, causing diabetes.

  • There are three main types of diabetes.

  • Diabetes type 1 occurs when our immune cells destroy the cells in pancreas which make insulin, resulting in less or no insulin production.

  • Diabetes type 2 occurs when pancreas cannot produce enough insulin or our bodies cannot use it well.

  • Gestational diabetes occurs in pregnant women.

  • Diabetes can lead to blindness, kidney failure, heart attacks, etc.

  • Hence, diabetic people should always maintain their blood glucose levels.

  • Why can't you use phones on planes?

  • Coz phones can fall out of the window!!

  • Naahhh!!

  • It might be because portable electronic devices like cell phones and tablets emit radio signals.

  • These signals can interfere with the flight controls.

  • They may also disrupt the communication with the air traffic controllers on the ground.

  • Besides this, cellular towers are miles below the airplane.

  • Hence, cell phones try to emit a stronger radio signal to detect the network.

  • This can increase the possibility of causing interference with the airplane electronic equipment.

  • Really!!

  • I didn't know that!!

  • Hence, portable electronic devices are told to be either turned off or to be kept on airplane mode or flight mode.

  • This prevents the emission of radio signals, thus helping to keep all the onboard equipment working properly.

  • Topic: Joints

  • Why do knuckles pop?

  • So that when we get bored we can pop them for timepass!!

  • Naahhh!!

  • A knuckle is a joint in the finger where two bones come together or connect.

  • This joint is filled with a fluid called synovial fluid.

  • Synovial fluid is a viscous fluid containing dissolved gases like oxygen and carbon dioxide.

  • When bones move, the synovial fluid prevents them from grinding against each other.

  • Wow!!

  • It is so amazing!!

  • Indeed!!

  • When we stretch or bend our finger, the space between the two bones increases.

  • This causes the synovial fluid to stretch, thus creating low pressure in it.

  • Now, as gases are less soluble at low pressure, the dissolved gases in the synovial fluid undissolve.

  • Resulting in the formation of a bubble, which we hear as the pop sound.

  • Topic: Ultrasound

  • Why is ultrasound used in sonar?

  • Hey!!

  • Looks like you are searching for a treasure hidden in a sunken ship!!

  • Why don't you use a sonar??

  • It will emit ultrasounds and help you locate the ship!!

  • You know what!!

  • I have a better idea!!

  • No!!

  • A music system will make ordinary sound!!

  • So, it is of no use!!

  • Don't fool me!!

  • I know that the music system is the right choice!!

  • See!!

  • You are not able to find the ship!!

  • Now, will you use a sonar??

  • Look!!

  • You easily found the ship!!

  • Do you know how a sonar could locate the sunken ship??

  • It was because of ultrasound.

  • Ultrasounds are sounds having very high frequencies which start from 20,000 Hertz.

  • So, is ultrasound used in sonar because of its high frequency??

  • Bingo!!

  • You are absolutely correct!!

  • Due to its high frequency, an ultrasound can penetrate to a greater depth.

  • Thus helping us to locate the depth of the sea, sunken ships, etc.

  • But, I'm not able to hear the ultrasound??

  • It is because human beings can hear sound frequencies from 20 Hertz to 20,000 Hertz.

  • As ultrasounds have frequencies higher than 20,000 Hertz, we cannot hear them.
