Domino engineer Hevesh5 is known for extravagant structures and extreme patience. Her latest project is a complex spiral that took a whopping 25 hours to construct. The amazing design has three segments that collapse in three phases: First the bottom floor, then the top white pieces, and finally the colorful walls. There's also some nice flourishes like swinging pieces and a small example of the domino chain reaction—when small pieces can knock over slightly larger ones.
Despite the 25 hours of work and 15,000 individual dominoes, the enormous structure only takes two minutes to completely collapse.
