Shocked quartz is not actually rainbow, those images are microscopic views of single shocked quartz particles! On a non-microscopic level, this is what it looks like.

A little bit mundane compared to those funky rainbow microscope shots if you’d ask me.

Glendonite star fossil

This fossil is not of an animal, but a mineral. When sea water temperature at the seafloor drops below ~4°C/39°F a carbonate mineral called ikaite will start to precipitate and grow forming bizarre shapes. Even though the original mineral will dissolve once it is buried, other diagenetic minerals will replace its form, making a glendonite.

Gledonite/Ikaite and its specific forming conditions allow geologist to approximate climatic conditions for the time period captured by the rocks in which this mineral is found.

Thanks to the flat exposure on the rock platform, we can appreciate this nature’s creativity.

Example from the south coast NSW, Australia.

the fact that we can map sedimentary units from space is really cool and also Mars is cool!

GUYS, I HIT THE JACKPOT. So my department is in the midst of organizing all the stuff and we’re getting rid of a bunch of rocks that we’ve had lying around in bins and LOOK WHAT I FOUND. It’s a copper ore, specifically a bornite (Cu5FeS4) vein. For reference, bornite is the peacock ore, and it’s even prettier in person than in the pic. I remember collecting little pieces of bornite from rock grab bags when I was a kid, but this piece is HUGE!

Let me tell you about my panda mini-washer

As an apartment dweller, this is a game changer. My current apartment doesn’t have a laundry facility and the closest Laundromat about a 30 min bus ride which is just not practical. The mini-washer is a life saver

The panda mini washer hooks up to the sink, is incredibly lightweight (about 28 pounds, so light even I can lift it) and easy to use. 

It has a surprisingly large capacity. The basket from the first picture represents about one and a half loads. The jeans took up a whole load while the rest filled the bin only half way. 

Here’s the inside. The left is the washer the right is the spin dryer. Yes, it even drys.

Basically you shove your cloths into the washer, fill it up with water and let it go. I use my shower head to fill it up so it goes faster, the sink hook up took about five minutes to fill the whole tub, with the shower head is is down to a minute an a half. I do it in three wash cycles, a five minute rinse with baking soda, a five minute wash with soap and a three minute rinse with water. You have to drain and refill between each cycle so it’s a little more labor intensive than a traditional washer. 

That’s the spin dryer. It’s about half the capacity of the washer so one wash takes about two loads to dry. The spinner is much more effective than I was expecting. A three minute spin gets my cloths about 90% dry. I hang them up to air dry for that last 10%. 

The machine cost me about 150$. When you factor in two dollars for the bus, five for the machines (per week), the mini-washer pays for its self after only about six months worth of laundry. 

I’m not great at expressing emotion, but I’m hoping you can tell how excited I am.  Let me just say that the panda mini-washer is great and I highly recommend it to anyone currently using a Laundromat.
