The original formula can be referred to at the bottom of this page. I wasn't getting any motion at all when heated. So, I had to make the oil lighter or the alcohol heavier.
Water is heaver than the oil and the alcohol.
So, I added a little water to the alcohol. This made the solution slightly cloudy. The change in weight was a success. I used three springs from the inside of ball-point pens for the heating coil. I stretched them out and attached them in a triangle form.
