I got a similiar problem. I used Epsom salts and Fairy liquid and was going to post instructions on here as it worked perfectly. But after two days the goo has started to stick to the side of the globe and is not moving. Any ideas why this started to happen?
really, I just added a little salt at a time and watched the activity, if nothing happened, I added more. I also guessed on the soap (you can see my failure picture from adding too much) I used CVS brand epsom salt (MGSO4) and I used some clear scentless soap. An update- It has worked perfectly so far, the only problem I found is that some of the wax is starting to stick to the globe.
