Calling all builders, tinkerers, and engineers...the Cambridge Public Library has been overrun by Leprechauns! 

Help us catch these mischief-makers by coming to the library to build a trap. You will get to leave your trap in the library to find out how effective your trap is. 

Come back the next day and see how many leprechauns you caught! "Trap engineers” will each receive a report on how successful the trap was, along with a small prize.

All materials will be provided, supplied by the Friends of the Cambridge Public Library.

This program is geared toward kids of preschool/school age, and registration is required as space is limited.  Please register each builder separately.
