Do Blasts Pass Through Obsidian?

I’m in a bit of a pickle.

It seems someone playing on my friend’s SMP server decided that it would be a good idea for him to do some testing with TNT.

Endless Sea of TNT

Now, he’s conscientiously set this atrocity up a reasonable distance from the rest of the construction on the server, so I don’t think that it will effect any damage in the other projects, but someone still has to get rid of it. Guess Who.

This is what I’ve come up with, as a means of surviving the cataclysm:

Obsidian Shelter

However, this shelter is of course, based on the assumption that since Obsidian cannot be destroyed by explosions, it will act as a barrier to their consequences. If I were to hide inside this shelter, would I emerge unscathed after detonating the TNT?


Anecdotally, from the explosion patterns on another question, I never saw a block that was further from the center being destroyed while another, closer block wasn’t. All my target blocks (redstone) had 0 resistance, so anything touching them should have popped them (though they do have a sort of resistance when they get destroyed).

The mechanics as described on the Explosion page over on the Minecraft Wiki state that they are modeled as rays originating from the explosion center travelling out until they are fully attenuated. If they all meet an impenetrable wall (obsidian), they can all be absorbed and nothing gets through.
