While many in the world are switching to creating inventions using 3D printing, the Belarusian enthusiast continues to amaze with his unique designs made of paper and cardboard. This time he assembled an organ, a wind instrument with forced air supply. The craft has only 11 white and 7 black keys. The air reservoir is an ordinary balloon. The air supply is carried out, as in a regular organ, by pressing a key, and each cardboard tube makes its own unique sound.
