A group that says it's based in Rome says it has been placing small metal boxes with currency notes inside in cities around the world to see what people would do with money they didn't expect to get.
In a reply to our story about the boxes found in Boston and Cambridge, which brought the two cities' bomb squads to at least three locations yesterday, somebody who says they're part of the effort writes:
Sorry for causing all the trouble, we did not mean to! We are doing a social experiment all around the globe in which we are giving away money in these boxes. The goal of it is to find out what people do with money they would not have had. We are more than happy that people already donated the money to charity.
Amy Brown, who found one of the 3x5 boxes with a globe logo on a bench near Harvard Square on Friday, said she and her boyfriend planned to use the $50 bill she found to buy some margaritas and street corn at their favorite taqueria.
An Instagram page has photos of the boxes in Cologne, Milan, Rome and Auckland and Wellington, NZ, and says more will be revealed on Sept. 9.
