The foundation of my house is made of boulders, do those count?

I have several dozen free of metal contamination that are in my turtle tank and aquariums. I found them on hikes, at beaches, and from lots of different regions.

I also have a bunch that have metal contamination (slag or natural deposits) which are in a jar because they kill invertebrates so can’t have them in the tanks.

Other than that I have lava rock on top of most of my plants.

Do driveways count? Because then I have a shit ton of rocks.

[–] Wren@lemmy.today 2 points 1 day ago

Absolutely. Let us know how many.

[–] TheSlad@sh.itjust.works 2 points 1 day ago

I have no idea. Not even counting my displayed collection, i have a pile of rocks on my kitchen counter, and two boxes of rocks on the floor, plus more rocks around in various places...

IN my home? Not that many, just the extra special ones. Sapphires and opal I dug myself, a few fossils that are kind of fragile, and some.. um..."spicy" rocks. In double containment.

In my office are tons of neat hand specimens I found over the years. A few in my car I haven't categorized yet. A decent quantity of B-tier rocks that I could still do something with around the yard. Ooh, and 2 different landscape collections I keep at work.

Oh, and then: I have a house in another town that I lived in for 15 years. That place is fully landscaped and half buried with rocks :D It's the "home base."

... how spicy? We talking sieverts?

[–] HorikBrun@kbin.earth 2 points 1 day ago

I'm used to measuring in mRem which is a whole body dose equivalent. But you're on the right track.

[–] TomMasz@piefed.social 3 points 1 day ago

Less than a dozen, but more than zero now that I think about it.

[–] CoolerOpposide@hexbear.net 2 points 1 day ago (1 children)

Literally countless. So many that they are decorating the homes and outdoor spaces of my family and friends

[–] Johnny_Arson@hexbear.net 2 points 1 day ago (1 children)

disgost Better not be stacking them.

[–] CoolerOpposide@hexbear.net 2 points 1 day ago (1 children)

Did you know it was me who started that struggle session? 👀

[–] Johnny_Arson@hexbear.net 2 points 1 day ago

Lmfao no, I just have passing knowledge of the most infamous silly struggle sessions and site lore and I did look it up. My favorites were Rock Stacking, and the fact that apparently there were struggle sessions about both (outdoor) cats AND dogs (pitibulls multiple times apparently).

I guess about 20? I keep some cool rocks I've found on trips as mementos in a bowl under my Buddha statue, well, two are cool pieces of wood.

[–] Jerb322@lemmy.world 3 points 2 days ago

Theses are just the ones in reach, a lot. To many to want to count.

[–] Perspectivist@feddit.uk 3 points 2 days ago

Just one. I picked it up because it was round and I didn't have the heart to leave behind.
