Elephants can hear through their feet.
They’re sensing these underground vibrations through their feet. Seismic waves could travel from their toenails to the ear via bone conduction.
We can allow people to hear what elephant hear by using this technique. We can follow the structure of elephants and build a vibration earphone connecting our shoes and our ears. When we wear this, we can hear the sound of the surrounding environment and learn about the world in this way.

my silicone casting

I tried some at first and they all failed because the clay I bought has sulfur. Don’t buy this clay!!!

The part that has connection with the clay never cures.

Then I tried with cardboard to make the mold. It works. This is the final outcome. I did not take photos of its procedure because my hand is full of silicone at that time.
You can see my design in this picture.

And this is what it looks like when inflated.

Then I cut it into 3 parts. However I cut some bubbles and it create some new holes. I have to cover the holes with new silicones and this is what it looks like.

It seems that it has the power to open and close itself. The air would force the 3 channel to go into different directions.

I fount that without a 3d printer and a degas machine, it is so hard to do silicone casting to control its shape. So I chose a very simple silicone casting for my final.
