Okay. So I just get my lava lamp previously today.
I don't want anything to happen to it but yeah...
Is it risk-free to leave it on for the 7-8 hours that I'll be sleeping?
And I call for to know now, back I go to sleep.
So yeah...
I'm only thinkig...
That might be safe because the store have their lava lamps on and they must have been on for AAAGES.
But yeah, how long do you believe??
