Materials + Tools
1 teaspoon sodium-alginate powder
2 tablespoons calcium chloride
5 cups water
electric hand mixer
2-3 plastic syringes
glass apothecary jars
food coloring - red, green, white
wooden spoon
1. Make Sodium-Alginate Mixture
Add 2-1/2 cups of room-temperature water to a mixing bowl (Image 1). Place the electric mixer in the bowl and turn on (Image 2), then add 1 teaspoon of sodium-alginate powder to the water (Image 3). Tip: The sodium-alginate powder will clump up, so keep mixing and increasing the speed until the mixture is dissolved and a thick, viscous liquid is produced (Image 4). Next, add red food coloring to the mixture to make organ-like colors. Stir the mixture together with a wooden spoon (Image 5). Set aside for later.

Sinister Specimen Jars: Create Mixture
First add 2-1/2 cups of room temperature water to a mixing bowl. Turn on the electric mixer and slowly add in 1 teaspoon of sodium alginate powder to the bowl. Tip: The alginate powder will clump up, so keep mixing and increasing the speed until the mixture is dissolved and a thick, viscus liquid is produced. Next, add red food coloring to make organ-like specimens. Stir the mixture together with a wooden spoon. In a glass cup, add 2-1/2 cups of cold water and 2 tablespoons of calcium chloride and mix with a wooden spoon until dissolved. Tip: The longer you let the mixture sit after its dissolved, the clearer the water will become.

2. Make Calcium-Chloride Mixture
Add 2 tablespoons of calcium chloride to 2-1/2 cups of cold water in a glass cup (Image 1) and stir with a wooden spoon until dissolved (Image 2). Tip: The longer the mixture sits after it's dissolved, the clearer the water will become. Next, use a plastic syringe to extract the red-dyed sodium-alginate mixture from the bowl (Image 3) and squeeze it into the calcium-chloride mixture in the glass cup (Image 4). This will create worm-like, long strings that appear as slippery organs (Image 5).

Sinister Specimen Jars: Add To Jars
Use a plastic syringe to extract the red dyed sodium alginate mixer. Then add it to the calcium chloride mixture. The syringe will create worm-like, long strings that appear as organs. Once all the faux creations are made, remove them from the calcium solution with your hands. Place the DIY organs into apothecary jars filled with water, then add a few drops of food coloring for add contrast. Add fake eyes, ears and fingers to the jars for a creepier-looking concoction and enjoy.
