First, that headline is in dire need of a comma or two. I didn’t know that volcanoes can spew different things. Mud volcano. Lava volcano. Refurbished iMac volcano. It is truly amazing what nature can produce. Also, I didn’t realize that volcanoes could have balls, let alone concrete ones.
I’ll give Indonesia an A for creativity and effort. I just wonder what happens when the volcano is full of concrete balls. In the future will we read a headline that says: Indonesia pummeled by concrete balls launched from constipated mud volcano. Tune in and see.
