The caption on panel #3 of the "DNA shot" graphic made me burst a blood vessel.

Here's how I extract DNA with fun kitchen science.

  1. Freeze.
  2. Add dish detergent and NaCl.
  3. Puree in blender.
  4. Thaw.  Stir *very gently* from this point forward.
  5. Add meat tenderizer and/or contact lens solution.
  6. Filter the mess to get mostly clear fluid.
  7. Layer rubbing alcohol over the solution.
  (If you use ethanol, make sure it's high-proof.)
  8. Draw DNA and RNA up from aqueous layer through alcohol layer with a kebab skewer.
