Solar Bell, a kite-like wind sculpture made of lighter-than-air materials — carbon fiber tubing and paper-thin solar panels — by Argentinian artist Tomàs Saraceno, in association with the Aerospace Engineering Faculty at TU Delft, The Netherlands.
The design of Solar Bell is based on a model of a modular tetrahedron, or four-sided pyramid, invented by Alexander Graham Bell during his early investigations into manned flight. Bell made important discoveries in the field of aviation and frame construction, and happened upon the strongest geometrical structure in the known cosmos—the octet truss—the same space frame that Buckminster Fuller later followed in his Geodesic dome. Saraceno breathes new life into Bell’s legacy by using the materials and knowledge of our time.
In August, 2009, Stefan Schöppers and his team succeeded in breaking the world record for the largest domino toppled in a chain that begins with a “regular”-size domino. Their largest domino, shown in the video above, is 6.40 m (20 ft 11 in) in height.
That record held until an 8m (26 ft 3 in) tall domino was toppled in a on the Dutch National Science Quiz TV show in January, 2013. You can watch that video here.
