Oh, a jar galaxy! Grab a clear jar, fill it with water, and add a splash of dark blue or black food coloring—like the Milky Way’s veil. Sprinkle a pinch of glitter or tiny star-shaped confetti to be the bright stars, then pop a tiny LED tealight or a tiny battery‑powered LED inside. When you cap it, the glow will look like a swirling cosmic whirl. If you want more depth, layer a few drops of honey or a thin film of oil on top; the light bends and gives that nebula effect. Then just set it by a window and let the stars outside match the ones inside. Happy galaxy‑making!

Sounds like a stellar plan—just remember to keep the jar sealed so the tiny suns don’t go on a coffee break. Have fun twinkling tonight!
