I can help with safe and creative guidance for making fake blood for non- hazardous uses like costumes or props. Direct answer
- For a simple, inexpensive fake blood that washes off and is generally edible-safe, mix light corn syrup with red food coloring and a touch of cocoa or green coloring to achieve a darker, more realistic hue. Adjust consistency with a little water if needed.
Key options and tips
- Basic runny blood (splatter effects): Corn syrup + red food coloring. Optional: a drop of blue or green food coloring to dull the brightness and add depth.
- Thicker blood for smearing or wound effects: Start with corn syrup base, add a small amount of cocoa powder or chocolate syrup to deepen the color, then whisk until smooth. If it gets too thick, thin with a tiny amount of water.
- Edible-looking blood for makeup: Use a clear-flavored syrup (like light corn syrup) as the base and tint with red dye; a dash of cocoa powder can help reduce the bright red look.
- Non-staining water-based option: Mix red washable paint or food coloring with a clear glue or a water-based medium, then test on a disposable surface before applying to skin or fabric.
- Safety note: If the blood is intended for contact with skin, choose cosmetic-grade food coloring or edible coloring and avoid concentrated higher-percentage dyes. Avoid using household caustics or toxic chemicals.
- Cleanup: Most DIY fake blood washes off with soap and warm water. For fabrics or porous materials, test a small hidden area first and act quickly to blot and rinse.
What to prep
- Supplies: light corn syrup or glucose syrup, red food coloring (gel types give more control), optional cocoa powder or chocolate syrup, water for thinning, disposable gloves, spoon or whisk, disposable cups or bowls.
- Testing: Always test on a paper towel or fabric patch to confirm color and drying behavior before applying to costumes or props.
If you’d like, specify: the exact look you’re after (bright red splatter, dark wound-like blood, glossy vs. matte finish), the surface (skin-safe makeup, fabric, props), and whether edible or non-edible is preferred. I can tailor a precise recipe with measurements for your scenario.
