Making oobleck is a fun and simple experiment! Here's how you can make it:
Ingredients:
- Cornstarch
- Water
- Optional: Food coloring (if you want colored oobleck)
Instructions:
1. Mixing the Ingredients:
- Start with a bowl or a container.
- Pour cornstarch into the bowl. The amount depends on how much oobleck you want to make, but a good starting point is 2 parts cornstarch to 1 part water.
- Add water slowly while stirring. You want to achieve a consistency where the mixture is liquid when you stir it slowly, but feels solid when you apply force quickly (like squeezing or tapping).
2. Adjusting Consistency:
- If it's too runny, add more cornstarch.
- If it's too thick, add more water.
3. Optional: Adding Food Coloring:
- If you want colored oobleck, add a few drops of food coloring into the mixture and stir until the color is evenly distributed.
4. Playing with Oobleck:
- Once you have the right consistency, oobleck is ready to play with! It behaves like a liquid when you handle it slowly, but if you squeeze it or press it quickly, it feels solid.
5. Cleaning Up:
- When you're done playing, oobleck can be messy. Clean it up by scraping it into the trash (not down the drain) and wiping the surface with a wet cloth.
Oobleck is a non-Newtonian fluid, which means its viscosity (thickness) changes depending on the force applied to it. Have fun experimenting and playing with your homemade oobleck!
