To make the blood used in our film we used the following ingredients:
red food colouring
blue food colouring
yellow food colouring
We started by pouring the golden syrup into a bowl followed by water and stirred. At this point I added the red food colouring and the corn flower giving it the strong red colour and making it less transparent. After, I added a small amount of yellow and blue food colouring to make it darker and more realistic. It took a few attempts to get right. One problem I did have was making the blood thicker, this was a problem as we needed it to stick to the walls and it did not, we resolved this problem by putting more corn flower in and filming very quickly. We additionally found that the blood faded in the white clothes, this was fixed by putting the red food colouring directly on where the wound should be, giving a more realistic effect.
