Who wants to see even more of my Cool Rocks?

image

This amazingly bright blue rock is apatite, and yes, that’s its natural color!  That texture is neat too, like little cracks in stained glass.  This one’s been carved into an egg, because I’ve been collecting eggs and spheres recently.

image

Speaking of spheres, here’s some agate.  Check out that cool banding!  This one has a little cap of quartz on top.  Quartz and agate like to grow together, because agate is actually a type of quartz.

image

Look at this really sparkly rock!  Astrophyllite forms these thin, tiny crystals that look like tinsel.  They’re so fragile that they break off in my hands when I touch them!  Sorry, buddy.  It’s just for the photo, and then I’ll put you down.

image

This green kyanite has little streaks of blue kyanite hiding inside it!

image

Picasso marble is a COOL ROCK.  It started its life as limestone, and slowly metamorphosed into pale marble streaked with colorful iron oxide.  That name is all wrong, though.  Clearly, that’s a Jackson Pollock.

image

This is alligator quartz!  That scaly pattern of overlapping crystals looks like the skin of an alligator, doesn’t it?  These shapes form when the quartz’s microscopic crystal lattice is damaged, but it keeps growing anyway.

image

This little guy is a Herkimer diamond.  It’s not a diamond at all, but a type of quartz that gets its name from its diamond shape.  It’s neither cut nor polished; Herkimer diamond comes out of the ground looking just like this!  I like all the little air bubbles trapped inside of this one.

image

Obsidian is an igneous rock, meaning it came from a volcano!!!

image

Serpentine!  It’s Very Green!  It’s got blotches and patterns and streaks!  Do you see all those dark, metallic little spots?  Those are pyrite inclusions!  All the pyrite in this sphere makes it super heavy.

image

Sticking out of this chunk of quartz is some colorful watermelon tourmaline!  The way tourmaline can change color as it grows is so cool.  (And also looks a little bit like candy.)

image

These are my Blobs of ocean jasper, which might just be one of my favorite rocks in the entire world.  Just look at it!

image

Aaaah, those patterns!!  Ocean jasper is an orbicular jasper, meaning it grows in little orbs.  When they’re cut and polished, their cross-sections make these characteristic fisheyes.

image

There tend to be big gaps between the orbs.  Usually they fill in with quartz or agate, but sometimes they stay empty, and you get these tiny geode pockets lined with sparkly quartz druzy!

image

When the orbs are suspended in transparent agate, it’s called jelly ocean jasper!  My white blob has a huge patch of clear jelly.  My green blob has a little window of teal jelly.  Every time you look at ocean jasper, you see something new.  What a beautiful rock!!

(You can see more of my rocks over here!)

buddy, i get so excited every time i see a new one of your cool rocks post. thank you.

So, we’ve all seen the posts about how alcohol, caffeine and spicy food is viewed as horrifying poison across the galaxy, and how aliens are all suitably horrified when they see us consume it. 

Tell you what I haven’t seen mentioned, but which is also varying levels of toxic to most not human animals? Theobromine. Normally found in chocolate. 

Like, can you imagine being captured by aliens who are planning to poison you to send a message to your crew. They spend some time describing this poison, including the risk of internal bleeding, vomiting, seizures and heart palpatations as you get steadily more and more afraid. 

Then the executioner brings out a mug of steaming hot chocolate. 

I don’t know about you, but if i’d been in space for an indefinite amount of time on what are presumably carefully calculated rations, I would be kicking aliens out of the way for that cup. 

Just drink down the whole thing without breaking eye contact and watch them lose it.

I was amazed at the candour JEV, Sam and Ant gave me for this one – about coming from career nadirs and recovering in the high-stress, high-difficulty Formula E. 

When the series first began, it was considered a surefire failure by a lot of people. And the drivers entering were considered idiots, greedy or desperate – depending on their previous racing record, their pay check or the recency of them getting publicly insulted by Helmut Marko.

I asked one of the third category, now two-time race winner and BMW factory driver Antonio Felix da Costa, what he thought of the series then: “When I touched a Formula E car for the first time I wasn’t convinced. But I was going through a really hard time in my life – I’d just lost out on my Toro Rosso seat, which had felt like a sure thing at the time so I was a bit frustrated. I had a test in a Formula E car and I just thought ‘****, I’m only going downhill from now.’”
