I was watching my lava lamp today; I turned it on, lay down next to it, and just watched it. After about 20-30 minutes it was glowing red-orange, I haven’t seen it do that before. And after another 5-10 minutes it started making tiny bubbles. I love to see it at this point, where it makes tiny bubbles, then they get colder and fall like a bubble shower. But then, after about 5 more minutes, I saw that the bubbles had bubbles - there was air inside - and then the bubbles started popping! The bubbles would pop and make a tiny explosion! Once or twice they popped and blew up into about 30 half-gone, eraser-sized bubbles. I watched for about 20 minutes until it stopped. It was the first time that I have ever seen a bubble within a bubble; it was cool!
-P.S. sorry about what looks like
bad grammar (lay down next to
it, other), but I looked it
up and it is proper grammar
