Just got my wife a Grande from Lava World. It's the yellow/blue combo.
It arrived by Fedex & since it's really cold out I let it sit to get it to room temp.
Next day plugged it in & it worked great ! However, that's the last time it worked that way. Now what happens is after about 2 hours it starts to run well then becomes one
big blob on the bottom. Sometimes it's 4 or 5 big blobs. It will send off a little lava to the top sometimes but for the most part sits there at the bottom.
This is our first lava lamp so I figured I'd ask the experts (meaning you folks) here.
