Last February, Mike and Steve Perrucci built and then toppled a course of several thousand dominoes in the main gallery of the Brattleboro Museum and Arts Center, and the event was so successful that they are back to do it again. Domino Toppling II: Brattleboogaloo is twice as big, with around 15,000 colorful dominoes performing stunts and snaking around the museum exhibits. The dominoes fall at 5:30 p.m. and doors open an hour earlier for visitors to see the course while it's still standing. The person closest to guessing the number of dominoes used has the honor of starting the chain reaction.
Feb. 27, 5:30 p.m., Brattleboro Museum and Arts Center, 10 Vernon St., Brattleboro, Vt., (802) 257-0124, www.brattleboromuseum.org.
