Clean and dry the pieces.Start by removing any labels and washing the container and miniature pieces you’ll be using. Test the waterproofness of the container by filling it with water, attaching the lid, and turning it upside down. If it leaks, find our tips for sealing at the end.
Glue miniatures to the container lid.Use the outdoor adhesive to attach the miniature pieces to the lid. The should be far enough from the edge that they won’t keep it from closing easily. Allow the pieces to set until the glue is completely dry and the pieces do not move. This may take several hours, depending on your adhesives - ours took about 2 hours.
Add the water and glitter.When everything is dry, add distilled water to the container, leaving room for the miniature pieces. Add a pinch of glitter.
Close and seal the container.Carefully place the lid on top of the container and screw it closed. If your container leaked at the beginning, you may want to add more glue around the screw top grooves. This will make it water-tight, but you won’t be able to open it to make changes later. We also tried plumber’s tape, which worked okay, but probably wouldn’t make it permanently leak-proof.
