Strawberry DNA Extraction: How To

First we put the strawberry into a plastic bag with some of the 'DNA Extraction Liquid' and mashed it into a pulp.

Next, we put a coffee filter over a graduated cylinder and poured some of the pulp into the filter paper. We let that drip into the cylinder for a few minutes.
After we had enough liquid we transferred that into a test tube so that we could see it better. 

We then added some rubbing alcohol to the test tube and watched DNA extraction happen before our eyes. 

Once we saw some of the DNA, we used a little hook to take some if it out of the test tube. The DNA we took out was a sort of goo.
