Introduction: "Bleeding" Ballistic Gel Target

About: Mechanical engineering student. My main interests are in biomechanics, robotics, and prosthetics.

After watching a lot of Deadliest Warrior episodes and getting bored with shooting paper targets with my pellet guns, I decided to make a target with a little more reaction. This is a "bleeding" target that will spill fake blood once shot. This ballistic gel is perfect to test experimental homemade weapons or covert gadgets. Even with a low budget, this is very inexpensive to make.
Enjoy :)

Step 1: Supplies

These are the basic supplies that you will need:
1. Unflavored powdered gelatin (I used a Kroger brand but many use the Knox brand)
2. Sandwich bags (the ones that don't have a zipper)
3. Maple syrup or Corn syrup
4. Red Food coloring
5. A Container that will allow the blood bag to be covered fully
6. String
7. Cooking spray
The other supplies will be added along

Step 2: Making the Gelatin

First we are going to make the gelatin.
For my bleeding target i decided to use 2 cups of gelatin, but any amount can be used depending on your mold.
All you have to do is dissolve 1 oz (4 packets for me) of gelatin for every cup of room temperature water.
After you have done this, pour the mixture into a container (this will not be the final container so you can use any plastic container) and refrigerate for 3 Hours.

Step 3: Making the Blood Bag

This blood bag is made from a mixture of syrup, water, and red food coloring.
For my blood bag I used a 1/4 cup of syrup with an 1/8 cup of water and a squirt of red food coloring.
I mixed it all together in a cup and poured it in my sandwich bag.
I then tied a knot in the bag so it was sealed (cut the excess plastic off). You can mess around with the ratios to make as thick as you want.
Next tie a piece of thread to the tip of the bag so it can be suspended from the container

Step 4: Put It All Together

After the 3 hours are over, take the gelatin (still in the container) out of the fridge.
Set a pot to with water to boil and then turn off the flame. Set the container of now solid gelatin in the pot and let it become liquid again.

First, spray your container with cooking spray so the gelatin won't stick.
Tie the other end of the string from your blood bag to a pencil or stick and suspend it in your container.
Pour the liquid gelatin into the container and make sure it covers the blood bag completely.
Put back in the fridge for at least 12 hours

Step 5: The Fun Part

Once the 12 hours are over CAREFULLY take the gelatin out of the container and cut the excess string off.
I am going to test the gelatin with my Daisy Powerline 880s pellet gun.
Then shoot the heck out of it with my Crosman 357w pellet pistol :)

The Daisy is shot from 5 yards away at 700 fps.
First with Crosman pointed pellets, Then with Crosman Hollow point

The point pellet just made a small entry and exit wound but the hollow point destroyed it.
