I am not very experienced in Lava Lamps and I bought a 52 oz from Spencers. Its a clear liquid red fluid one. Im wondering if the 40 Watt Bulb it came with is too hot for it because it runs hot and after about 3-4 hours all the goo collects at the top then falls to the bottom and becomes a huge glob. I got a bulb that was 30 Watts but it wasnt hot enough cuz the goo didnt rise after about 4 hours. I have it off now, Im wondering what to do >.< Is it overheating with the 40 Watt? Or is it just something new Lava Lamps do? Also, is it bad that the goo has air bubbles in it? is that just something new lamps have and will go away or is it something I should be worried about? I have taken great care of the lava lamp so far, I havent knocked it down or anything. Any help would be appriciated. Thank You.
