Mayor Thomas M. Menino presents the Fall Pumpkin Fest on the Boston Common Frog Pond on Sunday, October 27th from 4:30 – 6:30 pm.  Bring an 8 inch or smaller carved pumpkin to the Frog Pond to float and help set the Pond aglow at twilight.  Interact with spooky ParkSCIENCE experiments from the Massachusetts Horticultural Society, Bio+Art Collaboration, and Boston Best Bees Company.  Wear your Halloween costume and participate in the Halloween Parade led by Frog Pond Freddie.  Watch Rosalita’s Ghoulish Puppet Show, a dazzling magic show by Kayla Drescher Magic, and a fun bubble show by “Bubble Man” Jim Dichter.  Try scarily delicious treats, refreshments and games from National Dairy Council’s Fuel Up to Play, Archway Cookies, New England Coffee, Magic 106.7 and more.  Bring donations of canned goods for CANshare, Mayor Menino’s annual food drive for those in need.  ParkSCIENCE is funded in part by a Green Parks Green Kids grant through a partnership between the National Recreation and Park Association and the National Recreation Foundation.  Free.
