Look what I finds!

I was kind of quoting LotR in the title.

Anyway.

 I found a fake blood tutorial when I was browsing deviantART. Because, that's what I do in my spare time. I'm going to say this: please use vegetable gelatin (agar, which is Japanese, for example). For me? Because I went to all that trouble to post a link here?

And beware of stains.
And please don't use it to fake murder scenes and cause mass civilian trauma.
