Wax is running in columns up the side
Some of you amazing folks may remember me asking a couple weeks ago for lava lamp recommendations for my daughters birthday. I got so much awesome help and I went with a Grande. My daughter absolutely loves it, but it's not flowing right. The wax forms these long columns up the sides with very little doing the lava blob thing that we expected.
I'm afraid her room may be too cold, but it's within the "ideal" range that I found in the info booklet that came with it. Around 75 during day and 70-72 at night. It is near a window with the shutters closed but we live in a hot climate so a cold draft isn't an issue from the window.
I let it run for a couple days straight hoping that would get things going but it just got worse.
I turned it off for a day and wax just stayed clung to the sides.
I freed up some by using a hair dryer on it and it's currently wrapped in foil. If that doesn't work, any suggestions would be appreciated.
