To do this you will need:
A plastic rod
ethanol
a mixture of salt, water, and shampoo
a plastic baggy
a strawberry
a test tube
a funnel
cheese cloth
a squirt bottle
1. Cut the top of the strawberry and core it and mash it in the plastic baggy for a couple of minutes
2. Add some of the salt-water-shampoo mixture to the baggy and continue to mash for another minute or so
3. Put the cheesecloth in the funnel and poor the strawberry gunk into the funnel to let it filter into the test tube until you have about and inch of strawberry solution
4. Slowly use the squirt bottle to fill the test tube up to half way with ethanol on top of the strawberry solution.
5. Use the rod to touch the strawberry solution where it meets the ethanol and start to stir slowly. You should see the DNA starting to clump.
