Paint each foam ball to represent a planet, using swirling strokes to add texture and depth.
Let the planets dry fully, then paint the base black and lightly splatter white paint for a star effect.
Push one skewer into each planet, adjusting height so larger planets sit slightly higher.
Insert the skewers into the foam base, arranging planets around the Sun in order.
Write planet names on the labels and glue them near each planet for easy identification.
