We made false belly from silicon and pour a special liquid inside it. My partner Maxim Ivanov helped me to make an electronic device with array of sensitive microphones and amplifier. As a result, visitors can hear sounds of environment with headphones in real time, as if they are underwater. At the same time they can hear my heart beat, rumbling stomach, and me singing something like a lullaby. I tried to reconstruct situation when visitors were babies in mother's womb. I believe that we have sound memory. When you listen to your favourite song you can go back in time emotionally and remember what happened when you were listening this song for the first time. I considered my sound design can help come back to the beginning of life and understand something very important about yourself and about your inner child.
