iOS beta 10.1

Swoosh salt water in your mouth to collect some cells from your cheeks. Spit it out into soap water solution in the clear container, to dissolve the cell walls and extract the DNA. Pour methylated spirit on top of the soap water, and wait for the white swirls to appear at the interface. That is DNA, and it is only visible for a short time. Since DNA precipitate is less dense than the rest of the cell, it will rise above the soap water into the methylated spirit solution. Note: methylated spirits are HIGHLY poisonous, even though they smell like sugar cane! Label the methylated spirit bottle, and keep it in a locked cabinet.
