Marbles is hosting its annual Halloween party also this Saturday evening, from 6p-9p. Note that tickets are required, even for members, and that Marbles closes at 4p that day in order to prepare for the event, so you can’t go early and just stay.
Marbles as always puts a science/museum twist on the event, which includes among other things a Mad Scientist Lab and Spinning Spider Science. Showing up in costume is highly encouraged!
Purchase tickets ahead of time if you can, they are $8 in advance, but $13 on the day of the event ($10/$15 for non-members).
