Methylene blue dye is generally used to treat urinary tract infections and as a staining agent to make various bodily fluids and tissues easier to see during surgeries or x-rays. When consumed in small amounts, it turns poop and urine a greenish blue color.
When taken in large amounts, you can see what happens in the photographs above.
During an hour-long performance called Blue Remix, artist Yann Marussich sits motionless as the blue dye seeps out of every part of his body. It even begins coming out of his pours in tiny droplets.
Side effects of methylene blue include dizziness, nausea, headache, mental confusion and profuse sweating.
