What happened in this video? An explosion?

What happened in this fail video at 3:14? The video is a bunch of dash cam clips of mostly car accidents. It’s not too grisly to watch but be warned that some people do get injured.

I see in the comments that people are speculating that it is a mortar shell from the Ukraine conflict.

Almost looks like a pipe under the road exploded

Too quick to tell. As an aside, I was impressed by the motorcycle flip at 2:31.

Aye, that’s how it looks to me: like something under the road went kablooey.

Bah. That was just okay; this is a truly awe-inspiring motorcycle flip!

No idea on the explosion, but it seemed a bit, er, slow for it to have been some sort of military explosive. Gas leak igniting or mud volcano, maybe? Otherwise, I don’t have any idea what else it could be.

My favorite from the clips is the very last one, with the helium balloons popping out of the trunk.

I’m impressed with the woman at 3:45.

That’s her “Congratulations, you’re in an accident!” balloons

Me too.

‘I was almost squished like a bug! Ah well.’
