Q. Are glow sticks that were turned on before Shabbat and will light for a few hours muktza? Can one move them to another room?
A. See questions above. Horav Shlomo Miller’s Shlit’a opinion is that even if there is a possibility that when moving them, a further mixing of the chemicals in them may occur and result in an increase of the light they emit, since it is not a certainty and therefore not a “p’sik reisha’ and it is also not intentional, it would be permitted to move them. Therefore, the lighted glow sticks are not muktza.
