A sweat sample was collected and the sample contains no bio-hazardous material.
Finally, for the blue paint, printmaker Bambo Sibiya donated his tears. Paper Tear Flo strips, usually used by ophthalmologists to diagnose dry eyes, were placed in Sibiya’s eyes. Onions and menthol balm were then used to make the artist cry, with the tears being drawn up into the strips. The strips were placed in collection tubes, buffer solutions added and the tubes vortexed to extract the tears into the buffer solutions. The few viral infections (like cold and flu viruses) that could possibly be spread via tears were rendered non-infectious through the extraction process.
