Radio shaak sells a 100 power microscope for about 15$ When you turn the little wheel to focus and get a clear view ,the difference between clear and milky or cloudy becomes easily identified ,even at different angles they don't change. Make sure you are looking at the little bulb on the top not the stem.Some may have stems and no bulb on the end and these may not turn cloudy.If you dont have a radio shaak,check the internet like amazon.com.
