breaking lava chemically?

[Ccat]

I have read about expanding chemicals that will break up concrete.  You fill a drilled hole with this slowly expanding chemical.

Has anybody tried this to break lava?

It's worth a try I suppose, I personally don't think it will work, and here's why:

Concrete is pretty much solid. No bubbles, no place to expand. If you "make a space" by filling a cavity with a unstoppable expanding force, the concrete will make room by opening a crack and propagating that crack.

Lava, most lava, is full of bubbles. The expanding stuff will just crush the adjacent bubbles, and leave the rest of the lava alone.

Only lava I can see it working on is blue rock, which is essentially bubble free cooled lava.

Ummm yep. You may be right.

Olohana170 (used to be known as Bananahead before the punaweb change after the hack)  has been doing this for a long time.  That is being offensive in his/her posts and drive to only plant endemic plants.  Absolutely nothing else but the plants that were here when the native Hawaiians were the only ones living here or you are... insert adjective.  I have an adjective for you coming up.

When will they learn you can attract more flies with honey than vinegar?  You don't have to be an asshole about it Olohana.  Posting opinions are fine but we all know the cliche about opinions...

Gunpowder is just a bunch of chemicals:

It uses what is essentially water and a shotgun shell and fracks rock into rubble.

Obviously we need to frack the lava enough to plant our albizia. It captures carbon and creates a ton of biomass, unlike the lazy indigenous/endemic rubbish that takes years to grow to scrub-brush height on the surface. Remember the cool tree-tunnel we used to have on Kapoho Rd before hurricane Iselle? That could be the whole island! It might finally starve out the metrosideros polymorpha and dicranopteris linearis plaguing our neighborhoods!

Seriously though, that looks neat Terracore. They don't have a price posted, but in the long run that would have to be cheaper than the expanding cement.
