If you can't shop from these companies I am sure you can google your way to a local supplier for the materials.
Gel blood This is also very simple. Just take the blood you just made and mix it with a thickening agent until it gets as thick as you want it. My favourite thickener is Cabosil which is a fumed silica. It is also known under the name Aerosil.
You can find this in most boat making shops. It is used for making polyester and epoxy thick for making a gel coat for the first layer of a boat. Go and check in your local boat shop and they will probably be able to help you.
I use Cabosil for a lot of things. It thickens everything expect water! Use your imagination!
Well, how do you get it off?? It's not that hard if you know how to. The best thing about this blood is that the sorbitol crystallizes if it's cold. The crystals will wrap the color pigments inside themselves.. This means that if you wash the skin or clothes in cold water it's less likely to stain. I also always use shampoo instead of soap as the pH seems to help to get things off. A cold machine-wash gets it off from most clothes. But no guarantees!! Try first before smearing that $2000 suit!!
