Broken Table is based on the interest to try to capture and freeze a normally explosive event. The entire table is cracked, yet stays in place, stably.
Tempered glass is under extreme internal stress - If any part of the glass is brought to its breaking point, the entire surface will shatter into tiny pieces. A nail is hammered into the side of a sheet of tempered glass, which breaks into roughly 100,000 pieces in about 1 millisecond. Normally these pieces would fly in all directions, but here they are contained with other 1/8" thick pieces of glass (and tape around the edges). Overall, the table is 3/8" thick, with an aluminum lining to hide and contain the edges, and a simple aluminum frame.
