Yeah,your right . The can I used had the seal broken and with the high humidity here in East Texas it must have absorbed a lot of water. A few of these cans are noticably lighter , so I can assume these are the ones that need to be discarded. I took a sample of one without adding castor oil and it had major water bubbles.I checked one that was full and it was perfectly clear, so as soon as I get some more castor oil I will try it again and let you know how it turns out.
