We used many different materials to make the fake blood but the one that worked the best for us was the gravy blood because of the colour and its consistency. The worst one was the peanut butter blood because it was very solid and can not be used for many scenarios in filming. Severed group made the gravy blood and got the perfect colour and decent consistency. We could have improved by using hot water and mixing it more vigorously so that all of the lumps were gone.
