Hank and Michael Meet an Alien: SciShow Talk Show #4

What is the goal of the "Stump Hank" segment?

• To introduce a new animal species.

• To challenge Hank with a difficult science question.

• To discuss the speed of light.

• To demonstrate Morse code communication.

Why can't a long pole be used to communicate faster than the speed of light between Earth and the Moon?

• The pole would be too fragile to withstand space travel.

• The Earth and Moon's movements would make it impossible to keep the pole aligned.

• Information travels through the pole at the speed of sound of its material, which is slower than light.

• Morse code signals would degrade over such a long distance.

Which of the following materials allows sound to travel through it the fastest?

• Air

• Water

• Wood

• Steel

What type of animal is Kemosabe, the special guest introduced in the video?

• A hedgehog

• A porcupine

• It has very soft fur for cushioning falls.

• Its feet turn sideways and it has a prehensile tail.

• It can fly short distances between branches.

• It has sticky pads on its feet like a gecko.

What makes a porcupine's quills difficult to remove once they are embedded in something?

• They are covered in a sticky substance.

• They are very long and flexible.

• They have barbs at the tip that prevent easy removal.

• They are made of metal.

How does the porcupine communicate when it feels uncomfortable or threatened?
