Banana Mixture

As you see here we have all of our ingredients to make our concoction.

DNA dissolves in water, yet in the alchoholit clumps up allowing us to see it.

Here we put the mixture through cheesecloth in order to strain outthe majority of banana matter.

As you can see here, the DNA clumpsquite nicely!
