Five senses

Taste of elephant

The baby elephant need much more time to figure out how to use their trunks. It can be almost a year before baby elephants really understand. A baby elephant is clumsily bending down to drink water directly with its mouth. But an adult elephants normally use their trunks to siphon up water and squirt it into their mouths, which helps them avoid such a vulnerable position.

I made a way to experience how elephant drink through their trunk. Firstly, I prepared a deep container with water and a straw. And then after I put straw into the container, use finger to block off the other side of straw so the water can stay in straw because of water pressure. Next step is to roll up the straw and send the water inside mouth. Drink it!

 

 

Smell of striped skunk

It possesses two highly developed scent glands, one on each side of the anus, containing about 15 milliliters of musk each. The smell could be sprayed about 800 meters. If sprayed on the eyes, this compound can cause a temporary burning sensation. It was like a mixture of perfume musk, essence of garlic, burning sulfur and sewer gas.

My experiment is using white pepper power to let people feel the strong smell and simulate how people will feel if they would actually smell striped skunk.

 

Sight of Frog

It is interesting that frog vision is somewhat crude because frog might starve to death while surrounding by his food if the food is not moving. Evolution has favoured vision that focuses on active and mobile objects.

Those two sets of pictures are took from frog’s view. Frog’s eye cannot see motionless environment, they could only see the moving things. If his food just stay in front of him without moving, then the frog will not be able to see. From the pictures, the moving “food” are snail and fly, therefore the frog could only see a small area of his vision.

 

 

Touch of cat

Cat paws are sensitive

There’s a reason why most cats object to their paws being rubbed. Because their little paw pads are extremely sensitive. They contain large concentrations of nerve receptors, making them finely tuned sensory organs that aid in hunting and maintaining balance. Because of these receptors, cats feel texture, pressure and possibly vibrations through their paw pads, helping them evaluate the liveliness and close proximity of their prey.

Thought experiments project

In order to let people feel the extremely sensitive touch feeling, people would be ask to install two little massager on their feet. The massager will start to shake if it can feel any movement surrounded. Once people step forward, they will feel the shake so they will have the special feeling.

 

Sound of Dolphin

The dolphin’s echolocation process goes like this:

1)  The dolphin uses nasal passages to make a click and sends it through its forehead, which focuses the sounds together into a beam before sending it into the water.

2)   When the sound hits an object in the water, it bounces back to the dolphin as an echo.

3)   The dolphin absorbs this returning echo through its jaw.

4)   A passage of fat from the jaw conducts the sound to the dolphin’s inner ear, which exchanges nerve impulses with its brain to interpret the object’s characteristics, such as size, shape and material.

Thought experiments project

Similar to dolphin’s echolocation process, if people could cover his eyes and handle a small ball in hand and each time when they are in a closed room they throw their ball to wall. If so, they could have a good idea of how far the wall is depending on how much time they need for the ball coming back to his hand. Also, from the speed of ball come back, people will be able to know about what the surface of the wall.
