Additive Color Mixing

Mixing light colors. Play with red, green, and blue light, and with their brightness. When overlapped and adjusted optimally, red, green, and blue produce…

Adhesive Air

Coandă Effect: How shape, position, and surface influence airflow. The Coandă effect occurs when fluid or gas jets deviate from their original flow direction…

Aeolian Landscape

«Aeolian Landscapes» Wind shapes the landscape, just like water and ice do. As the wind sweeps over the sand surface, dune-like ripples form. When their…

Air Bubbles

Like dolphins: forming rings that rise. By pumping air into the glass tube filled with water, air bubbles rise. They ascend vertically. Often in a straight…
