Hi, new to this website but, big fan of lava lamps =). I purchased this lava lamp at walmart and its a Lava brand lava lamp; anyways its a white color wax and blue liquid with a metallic plastic housing. My lava will melt but, it will not flow. I checked the coil and the lava is on it so any suggestions? Also its not shaken if your going to ask. If you would like to see a pic of it go to google and type in "lava lamp shape of cool". I appreciate any suggestions. Thank you.
