What is Hydro-Dipping?
Hydro-dipping, also known as water transfer printing or marbling (in this case nail polish marbling), is a fascinating and creative technique where colorful patterns are transferred onto objects using water and nail polish, or paints.
You can hydrodip all kinds of materials – any material that can stand being submerged in water will work for hydro dipping, including wood, metal, plastic, glass or ceramics.
This DIY method for hydrodipping involves filling a large container with water and adding nail polish to create a marbled effect on the water’s surface.
By carefully dipping the starfish into this mixture, the unique patterns adhere to the three-dimensional surface, creating a stunning, one-of-a-kind design.
The process is simple yet produces professional-looking results, making it a fun and engaging craft for all ages.
And here’s how you can make your own hydro-dipped nail polish marbled starfish. Follow along with these simple step by steps below…

Materials
- Starfish (available at dollar stores)
- Nail polish (various colors)
- Large container
- Water
- Wax paper
- Glitter (optional)
Instructions
- Gather all the supplies needed. Make sure you have everything within reach before you start the process.
- Prepare the Water Bath. In a large container, add water and fill it 3⁄4 of the way full.
Pour in nail polish colors one at a time, creating a marbled effect on the surface of the water. You may need to add more nail polish after 1-2 starfish get dipped. 
- Dip the Starfish. Carefully and slowly dip the starfish into the nail polish and water
ensuring it gets fully submerged to pick up the pattern. 
- Slowly remove the starfish from the water, holding it over the container for a few moments to let the excess water drip off.
- Place the starfish onto the wax paper to dry.
If you want to add a bit of sparkle, sprinkle glitter on the wet surface. 
- Dry Completely. Allow the starfish to dry completely for 24 hours.
- Repeat the Process. Repeat steps 2-5 until all your starfish are beautifully colored. Note that nail polish can stain the container you are using, so choose your container wisely.
This craft is excellent for both kids and adults. Young children will enjoy the dipping and swirling process, while older kids and adults can experiment with different color combinations and techniques. Always supervise younger children, especially when handling nail polish and water.
Tips for Success
- Experiment with Colors: Don’t be afraid to try different color combinations to create unique patterns.
- Use a Clear Coat: Once your starfish are completely dry, you can apply a clear coat to protect the paint and give them a glossy finish.
- Work Quickly: Nail polish can dry fast on water, so work quickly to ensure you get the best patterns.
Hydro-dipping is a fantastic way to add a personal touch to everyday items. With a little imagination and some basic supplies, you can transform plain starfish into stunning decorative pieces that look like they came straight from a galaxy.
So, gather your supplies, set up your hydro dip tank, and start dipping! The possibilities are endless, and the results are always amazing.
Don’t they look so pretty?
Happy crafting!
