Things You'll Need
70 percent isopropyl alcohol (rubbing alcohol)
A trip to the beach often provides an opportunity to collect shells and marine inhabitants, including starfish. A starfish typically has five arms, but there are more than 2,000 species of starfish. Some have six or more arms in a variety of shapes. Starfish make an interesting memento and can be a decorative object for your home. There is a simple process to properly preserve the color of a starfish you've collected.
Rinse a collected starfish under running water to remove the saltwater and sand. Pat dry the starfish with a paper towel.
Pour 70 percent isopropyl alcohol, also called rubbing alcohol, into a container. Add enough to cover the starfish.
Place the starfish in the container with the alcohol. Allow the starfish to sit in the container overnight.
Remove the starfish, and place it on a paper towel. Move it to a warm, sunny location.
Allow the starfish to dry completely in the sun for at least one day.
