I just bought a lava lamp on ebay after seeing how cool my friend's is. I've had it on for 1 1/2 hours and it still isn't doing much. then I noticed on the box it says it takes "2-3 hours" to warm up fully. somehow I think my friend's takes about 20mins. was I swindled?
btw fyi:
it uses a 40w halogen bulb and I don't know how many oz it is
