Thanks for the advice-I will check it out!!

Tim, You sent me an email about using baby oil and colored water for the wave machine, I replied, and said that the specific gravities of the materials would not produce the desired results. I was rethinking your suggestion and came to the conclusion that I was wrong. My logic was reversed. The heavier water would sink below the baby oil, as it should. I am buying some baby oil and will try it. Thanks again for your input. I apologize for my error.

Greetings! Glad to have you join us at Oozing Goo!
