Susan A. Bender,
Jim Hill High School, Jackson, MS
| Forensics teachers take note. Here’s how to make realistic artificial blood for blood spatter labs: - Pour one liter of water into a suitable container.
- Add 8 oz red food coloring and one 16-oz bottle of Karo® Light Corn Syrup.
- Mix thoroughly.
You must use Karo® Light Corn Syrup; imitations don’t work. For more realistic color, add a pinch of Congo red indicator powder. If you want to examine the artificial blood under a microscope, add a tablespoon of dry yeast. The spheres that form around the yeast granules look just like erythrocytes.
