14. Press gently onto the balloon while holding onto the twisted part of the filter. Keep pressing that balloon smaller until most of the solution is out.
15. Twist the filter ever more into the balloon area, but be careful not to tear the filter. Wring it out like a miniature towel. This procedure lets you get all but about 1-2ml out of the coffee filter. Note: In case you have doubts about what the brown residue is in the coffee filter, you can test it! Scrape the residue into a small clear glass vial or container. Add 5-10ml of methanol or acetone. The brown stuff will begin to turn white (filler) and the liquid you added will take on a tan tint. The white will stay on the bottom and will not go into solution. Your liquid will not turn yellow because there are no hormones in the residue. If you add some water to the methanol, almost all the white stuff will disappear! AS are NOT SOLUBLE IN WATER. (No applause, please) Discard the test products and pat yourself on the back for getting this far.
