What Is Cornstarch and Oil Quicksand?
This slippery quicksand is a stretchier twist on the classic oobleck (cornstarch and water). Mixing cornstarch with oil creates a unique, moldable, and fascinating substance that behaves a bit like wet clay or mud. Kids can squish, scoop, and sink their toys in it—just like real quicksand!
Why You’ll Love This Slippery Sensory Dough
- Messy but manageable: Less wet than traditional slime or oobleck, easier to clean.
- Open-ended play: Ideal for imaginative storytelling and jungle rescue scenes!
- Sensory-rich: Engages touch, sight, and even smell if you add cocoa powder.
- STEM-friendly: A gentle intro to non-Newtonian fluids and material states.
What It Feels Like
Think of a silky, slick mixture that stretches like soft taffy when you pull it slow—but snaps if you move too fast! The texture is both soothing and surprising. Add glitter, and you’ve got yourself a sparkling swamp your little explorers will love to get their hands into.
Ingredients You’ll Need
- 1 cup cornstarch
- 1/2 cup vegetable oil, baby oil, or mineral oil
- Optional: brown food coloring, cocoa powder, or sandy glitter
- Optional props: plastic figures, animals, spoons, scoops, jungle-themed toys
Tools for Easy Play
- A medium-sized bin or mixing bowl
- Spoons or spatulas for stirring
- Tray or plastic mat for mess control
- Apron or play clothes
Ingredient Variations & Substitutes
- Want a scented mix? Try cocoa powder or a drop of vanilla extract.
- Need sparkle? A touch of glitter brings magical shimmer.
- More texture? A pinch of sand or tiny pebbles adds grit—just know it’ll change the consistency.
- No baby oil? Any mild oil will work, though vegetable oil is a kid-safe favorite.
How to Make Slippery Quicksand
Step-by-Step Directions
- Add Cornstarch to Bowl
Pour 1 cup of cornstarch into a bowl or bin. - Mix in the Oil
Slowly add 1/2 cup of your chosen oil. Start stirring gently. - Stir Until It Thickens
At first, it’ll be powdery. Keep mixing—it’ll thicken into a stretchable, slippery dough. - Adjust the Texture
Add more oil if you want it slicker; more cornstarch if you want it firmer. - Customize the Look
For a muddy appearance, mix in a few drops of brown food coloring or a spoonful of cocoa. Add glitter for a magical touch! - Let the Play Begin
Press small toys into the mix and watch them “sink”! Scoop, stretch, and explore how the mixture behaves with slow vs. fast movements.
Pair It With:
- Jungle animal figurines for storytelling
- Mini dig kits or sand tools
- A book on deserts or quicksand for a mini science lesson
Tips for Success
- Start with less oil—you can always add more.
- Keep wet wipes nearby for quick cleanups.
- Store leftover quicksand in a sealed container for up to a week (if using vegetable oil).
- Encourage kids to describe how the mixture feels and behaves—it’s a great language and observation activity.
Storage Instructions
Keep your quicksand in a zip-top bag or airtight container at room temperature. If it starts to dry out, add a splash of oil and stir. Discard if it becomes too sticky or smells off.
General Info & Safety Notes
This quicksand is not edible—so always supervise young children. If you’re using baby or mineral oil, make sure to keep hands away from eyes and mouths. As always, wash hands after play.
FAQs
Can I use any kind of oil?
Yes! Vegetable, baby, or mineral oil all work. Baby oil has a nice scent, while vegetable oil is most kitchen-safe.
Is this the same as oobleck?
Nope! This version is oil-based, which gives it a silkier, stretchier feel—think “mud pie” meets sensory slime.
Can I make this in bulk for a party?
Absolutely. Just multiply the recipe and set up sensory stations!
