The 3 March 2003 issue of US News and World Report has a bunch of nice stories on the 50th anniversary of the discovery of the double helix structure of DNA by Watson, Crick AND Franklin. At one point, they provide a recipe on how to touch some DNA in your kitchen.

1) Mash a source of protein, for example, a handful of strawberries. Add in an equal amount of water. Throw in a couple of squirts of shampoo and a spoonful of salt. Stir gently.

2) Strain the mash through a wet paper towel or cheesecloth so you are left with a clear fluid.

3) Pour an equal amount of ice-cold rubbing alcohol into the fluid. You will see a cloud form. Take a chopstick or the handle of a spoon and twirl it inside the cloud to capture long, gooey strings of nucleic acid (DNA and RNA).
