Kryjówka dźwięków (Hideaway of Sounds)
- Justyna Mazur, Wojciech Kiwer

The huge black funnel can hold several people. Come inside! There, you will find a black box. Everyone can put their hands in it and create sounds. How does it work? You just put your hands in and hear sounds coming out from the top of the funnel. 

Justyna Mazur and Wojciech Kiwer
