This may be a reference to the Alien movies. The android characters were filled with a white lubricating fluid which they bleed like a human would bleed blood. If androids are among us, that may be an easy distinction, what color is their blood?

The 21 grams experiment refers to a scientific study published in 1907 by Duncan MacDougall, a physician from Haverhill, Massachusetts. MacDougall hypothesized that souls have physical weight, and attempted to measure the mass lost by a human when the soul departed the body. MacDougall attempted to measure the mass change of six patients at the moment of death. One of the six subjects lost three-fourths of an ounce (21.3 grams).
