Children experiment with color mixing, projected light and shadow play to make artwork, and use mirror blocks and glowing manipulatives for matching and counting. The sessions connect the science of light to the meaning of light at Hanukkah. Open sessions follow Tot Shabbat on Dec. 4 and Dec. 11 (10:30–11:30 a.m.), run during the Shine Bright Hanukkah Family Show on Dec. 6 (1:30–3 p.m., show ticket required), and on Dec. 11 alongside the evening Family Hanukkah Celebration. ## Similar picks in Seattle - [Hanukkah Family Show: Mark Nizer 4D Juggling + Laser Show](https://grassyknees.com/seattle/activities/hanukkah-family-show-mark-nizer-4d-juggling-laser-show--listing-49580a307015b55f58d0111f) — Sun, Dec 6 · 1:30 PM – 4:30 PM · Stroum Jewish Community Center, Mercer Island · Paid · checked Oct 16.
