I made some last night... It looked pretty real and it stayed wherever I put it. I used Karo syrup and it seemed thicker than some other corn syrup that I had. Thanks again to Thalius for sharing.
Hey guys this is my first post here, but i was just reading this and its a good idea but if you want something that will last on your PROPS then dont go with gelatin. if your doing blood on a real person then yes, you can use gelatin. heres how we do it at our haunted attraction--
then we also add a little pros-aid. (its a medical adhesive that we use for applying prosthetics) we add that because it is white and it gives it a little opacity so the blood is not that transparent.
mix it all together and your done, you can splat it on walls, props, anything. and because of the high gloss urethane that we added it dries but has that wet look that you were going for with the gelatin. the only thing is, this will last much much much longer than the gelatin. just dont use it on real people
