The residue created in this process contains Urea fomaldahyde, which is a known carcinogen, and Red phosphorus, which can be potentially harmful. The smoke you see is the red phosphorus vapourising caused by the heat produced through friction. However, it should be pointed out that red phosphorus can revert to white phoshorus under frictional heat. White phosphorus is highly toxic! Formaldahyde is used for embalming. It changes cell structure permanently. It’s ok for dead people but not for the living. Cell deformity can cause cancer. If you have to try this experiment please wear latex gloves.
