In trick candles however‚ they add an ingredient that ignites at a lower temperature then the paraffin wax. This ingredient is usually a pyrophoric metal(metals which ignite at extremely low temperatures).  MAGNESIUM is the most commonly used pyrophoric metal in trick candles‚ with the magnesium flakes embedded in the wicks. When you blow out the candle

The lysis buffer is prepared from squeezed onion mixed with salt and Pantene Pro-V Shampoo. The buffer degrades the protein enveloping the DNA found in onion and cheek cells Cheek cells are obtained from gargled gatorade. Extracts are then filtered and subjected to addition of chilled ethanol. DNA is insoluble in alcohol making it to precipitate‚ DNA is then extracted. Keywords: DNA
