Join us for First Thursdays (the first After Dark of the month) when we explore one topic in a vareity of ways. This is a weekly event for adults to encourage continuing education and wonder in the grown up mind. Excite your atoms at Glow, our annual celebration of ebullient lights and subtle glows honoring the close of the year. Bask in the mesmerizing gleams of special installations and kinetic sculptures, take a shine to illuminating exhibits, and show your sparkle with scintillating activities. OSA is very excited to share our various demos at the Glow-themed After dark!
