Now that Valentine’s day is rapidly approaching, have you considered presenting a romantic partner with some jewellery made from your spit? A research project at Aalto University, Finland suggests that you could. Oron Catts and Marika Hellman of the university’s Biofilia Lab explain:
“First, some water is held in the mouth for a moment and then spit out into a test tube. A protein cleaving agent is added to the water and the test tube is placed in a water bath at the correct temperature. When a drop of alcohol is added to the test tube, the water begins to form a strange white mycelium – made from DNA taken from your own mouth.
This unusual Valentine’s Day gift is complete when the DNA is taken carefully from the test tube and placed inside a heart shaped piece of jewellery.”
