Galaxy bottles fill the jar/bottle with water Put the ink or dye into the jar/bottle until you get the color that you want. make layers of cotton balls and glítter. Like this: cotton, glitter, cotton, glitter.
DIY Galaxy in a jar: Add water and acrylic paint (if your making it a Galaxy use purples, pinks and blues) Get cotton balls and soak them in the liquid After every colour place silver glitter Display and enjoy! Makes me think of Space Mountain-Disney
