Hi, everyone welcome back Kody's lab. So we're finally back at the mine you notice
I'm holding the camera because [canyon] couldn't be here today. She hate to take her cat to the vet anyway
I got a little thing going on right now, so let's say go to it
See I got some mirrors here, and I'm going to try to reflect the light from the sun into the mine
That'll be very interesting yeah
Let's get some natural lighting going. Okay so here's the primary mirror out in the sun unfortunately
We've only got a few minutes to do this because look at where the sunlight is, sun's going down
And as you can see it's reflecting that sunlight
Way off into the mine. Let's go in there now try out these other mirrors
Okay, unfortunately if I stand in the way lights going to be blocked
Have a look at this. That is bright!
Okay, set one of these up
Reflect the light to the back
Put this mirror here
See what it takes to reflect the light all the way back there. Yeah, see I get the light
Basically in the back of the my already very nice
Alright, let me I fiddle with this for a little while.
Okay, so there's the plants Radishes are still going strong
We got a spot o'light
Clear back here on the shovel
Yeah, if I take this other mirror
As you can see
There it is, light's all the way
To the back of the mine
Unfortunately, I think I'm losing most of my sun
Yeah, suns going down outside, but eventually
Maybe I'll set that main mirror up on a pivot that way during the day. I'll be able to have natural sunlight in here
Look at that dog over there
Laying in the sunshine
So it got me wondering what if I took this laser rangefinder
Because it uses a beam of light to measure the distance and bounce it off of the mirror to
The back of the mine would I be able to read all the way back there and get a direct measurement
Let's find out, let's turn this beam on
I'm going to put it onto that mirror
My hand 's too Shaky. I can't hold it still enough
Yeah, it just gives me an error
Let me a set this up and actually hold it steady, see if I can do this.
Okay so I got this beam
So that I know where to put it so that I can put it on that back mirror now if I push this button again
It gives me a distance of 25 meters
About that and that's starting from right here. Which is a couple of meters in
And then this was bouncing back to the back of the mine so that it gives me approximately the distance
That's cool as I will it actually do that
Okay, let's do something else
Right so as you can see I'm wearing a dust mask now
Let's do some mining so as you can see I've got me a pair of chisels and a hammer
I'm going to try to a single Jack and actually drill some holes
Or at least one hole I can't I want to see how long it takes me a drill a hole. that's this long
Where do I want to drill this in?
Maybe if I punched it in right here
Yeah, kind of at an angle down right in there that way I can blow this out and get access to this
continuation of the vein probably. sun has gone down completely
But you know it doesn't really change anything working inside the mine
It's dark in there anyway, and I brought some lights there. We go. How about that
I got a lamp there. You'll notice I'm actually charging it with this
Inverter here that I found out in the desert while meteorite hunting
I just brought in a battery here now of course I could charge this battery with a solar panel pretty easily and
this ought to run that light for
Probably a day or two. I've actually got a little camera set up
He right here is taking [a] picture once every five seconds or so as I thought it was about time
we did have another mine lapse
Okay, so let's just set this light up
And I'm going to pick a spot and start chiseling
Oh, shoot. I forgot my helmet again
Was using it on the beehive. Hopefully you safety officers won't be too concerned about that
All right, so there it is you can see this Rod has been driven in there pretty far
Surprised, how fast it actually went I got this hole
about 16 inches in
Well, you can see that
It's about 16 inches in and yes
I have been using the tape measure to pull the cuttings out of the hole
In fact pulling the cuttings out of the hole took longer than the driving the steel itself so yeah
That's a full 1 inch hole 16 inches into the rock
I'm going to load this with some explosives
I think I'm going to use a tannerite type mixture, but I'm going to modify it a little bit so it's even more sensitive
so it'll actually explode inside that small diameter and
That should move quite a bit of material at least hopefully
anyway, I've been up here for
Quite a while. It's probably after midnight right now
Well, I'm several miles from the nearest human and there's dogs barking outside. I don't know if you can hear it and
Sound of the inverter humming it's totally quiet
Definitely would be slightly maddening
Let's say I get a little bit better footage of this drilling process here
So you see I just put the drill bit into the hole
Then I whack it
turn it whack it and
Continue until it gets hard to turn because the cutting inside the hole make it difficult to turn it around.
okay now that I've
Gotten to the point where it's difficult to turn the bit I can start actually
mucking the materials out of the hole
So I was using a tape measure I've wisned up a little bit and I got me a little blower
It's the inflator for an air mattress
This should just fit in that hole
Stick that in there as far as it goes and then I'm going to give it a little puff
Blow the dust right out of the hole okay now the holes cleaned out. It's time to add the explosives
It's a fairly similar tan right so it's a little bit more sensitive a little bit more resistant
I'm just going to cram as much of this in there as I can there it is the hole is loaded
I guess it's time to evacuate the hole
Wire this up and touch it off, okay. We're ready to fire it
I've got the camera out here of the front of the mine
I'll be just over there behind the camera, and I'm just going to touch some wires to the battery
Let's see what happens
FIRE IN THE HOLE!
Well, that was a that was more powerful. Oh wow
no idea. What the camera caught
In fact, I'm going to watch that back right now. Will let this dust settle so it seems
I forgot to have the light on so it was mostly dark in the camera really didn't see much
That's too bad
But I'm sure it heard it
Look at this ominous that cloud of smoke coming my way here
That's interesting
Wow look at it billowing out of there. thats crazy
And it smells like nitrogen dioxide
So yeah, definitely was an ammonium nitrate based explosion
So I'm hanging out low down underneath the smoke with the gas mask on you can see there's a little mouse running around
we found it
Guess that stirred him out
poor thing
That's it
That'll probably an hour after the blast
There's still a lot of dust in the air, but it's not nearly as bad as it was it punched a hole all right
The only thing is it didn't really move a lot of material.
oh well
It's kind of encouraging because there's a large crack running through the material that goes the way down to this spot
So I definitely like weakened it
Perhaps a few more of those and I could have actually knocked out the tunnel another Few feet
All right
So you've seen it. There's a hole
And I and i dug it in a little bit lots of material here that I can work with
Let's get out of here
So unfortunately, that's all the time I've got for today
Hope you guys enjoyed one thing I'd like to mention in that last video is I actually said the wrong name
for a fossil. I actually found a Bryozoan but I called it a crinoid
But the Bryozoans are more net-like and I found a Bryozoan and I called it a crinoid
I'd just I wanted to clear that up
You know I I'm a geologist. So that's really embarrassing that I get messed that up, but hope you guys forgive me also
Hope you guys enjoyed and I'll see you next time
The end
