Overall, the purpose of this step is to break up the cell membranes and enzymes in the strawberry cells.
You may want to tip the bag one way. This will allow for all the liquid to flow into one corner of the plastic bag.
Hold the sticking-out corners so that the cheesecloth can’t slide down into the funnel’s tube. Another option is to simply hold the cheesecloth onto the funnel as you would hold a cup. Make sure your thumb and index finger form a circle.
This process may take some time, but there should be strawberry-colored liquid dripping into your beaker/test tube filtered through the cheesecloth. Continue until all of your strawberry slurry is squeezed out of the plastic bag.
For more convenient cleanup, make a little bowl shape with the cheesecloth as you lift it so that none of the strawberry waste falls out. You may need to use a paper towel to support the bottom of the cheesecloth as you carry it because some liquid may still be dripping
If you would like to preserve it, use the bamboo skewer to scrape the DNA out of the beaker/test tube. Then put it in a small plastic capsule or clear box. It may dry out over time, but should last a while
