In honor of the 50th anniversary of the Technical University of Eindhoven, Arno Pronk designed an inflatable donut to be placed around a chimney at the university terrain. 

The donut hangs at 30m height and is made of a polyester fabric coated with PVC. The shape of the donut is obtained and stabilized through air pressure delivered by an air compressor. The donut is attached to the chimney with cables. On the outside, the donut is provided with a print.

Students of the university involved

The donut is produced completely in our workshop by the students. Buitink Technology  supervised the project and assisted in the preparation of the work. Finally Buitink technology provided the space, the material and the machines necessary for the production of the donut.
