Speaking to Dutch news publication NL Times, an anonymous promoter said the club has developed "a special sprinkler system with pipes running across the ceiling and thus making us able to spray blood over the crowd." According to the source, the pipes have passed tests using "a substance resembling blood."
Real blood is intended for the sprinkler pipes, the promoter reportedly expressed.
"It is pushing the borders, but we want to see how far we can go," they said.
Blood Rave has released brief teasers to promote the freakish event, including an eight-second video demonstrating the club's overhead sprinklers.
Tickets for the secret, bloody rave go on sale Saturday, Sept. 5 at noon.
