my personfriend, for his sculpture class, used some of my blood in a piece made of magic mold, trash, and twigs. (he combined the blood with wood glue).
it's called "30 minute limit on consumption"
when we first mixed it it was almost congealing...really strange texture. then once it was applied the blood began to drip OUT of the glue!! and then by the time it came to present the sculpture to the class it was darkdark and dried (mostly). cool cool.
