Calm down bottle.
Fill bottle 3/4 way full of hot water. Dump into glass measuring cup. Microwave 4 min. Add glitter glue & glitter, mix very well with wire whisk. Pour into bottle. Shake and see how long the glitter takes to fall. If less than 5 min, add a bit of clear glue. If longer, add a bit more hot water. Glue the lid on and hand to the kids after cooled. (This pic the glitter is settled.)
