Bad day in the lab

00:00:12.459 --> 00:00:16.030
So, the experiment of today...

00:00:16.230 --> 00:00:19.210
So, what do we have?

00:00:26.996 --> 00:00:32.996
So, for today... we have to do an acid dilution with water. Alright

00:00:42.994 --> 00:00:47.975
Okay so... let’s begin. First, let’s sample some acid solution

00:01:07.956 --> 00:01:10.996
And then the water

00:01:11.046 --> 00:01:15.006
Okay, so the water is on the left and the acid is on the right

00:01:18.007 --> 00:01:23.017
Then, for the dilution we need 25 millilitres

00:01:23.960 --> 00:01:28.040
25 millilitres, so with the volumetric flask

00:01:28.494 --> 00:01:33.514
Okay so now for the dilution I need my little pipette

00:01:38.005 --> 00:01:41.995
Hello! I am sorry I cannot talk to you right now, I am in the lab so...

00:01:43.964 --> 00:01:45.984
What is it for?

00:01:47.027 --> 00:01:52.987
Pff I don’t know, it should finish around 6 pm so … Let’s say 6:30-7:00 pm.

00:01:54.005 --> 00:01:57.104
Listen, I have to hang up

00:01:58.945 --> 00:02:02.065
I can’t, really! Let’s discuss about it later

00:02:05.251 --> 00:02:07.351
Okay so where am I?

00:02:07.461 --> 00:02:10.952
I’ve got the water on the left and the acid on the right

00:02:11.245 --> 00:02:13.725
so I can start the dilution

00:02:14.785 --> 00:02:17.765
A bit of acid for the beginning

00:02:48.016 --> 00:02:50.986
Ok … Now a bit of water

00:03:03.722 --> 00:03:05.533
So, to make up to the mark I need a wash bottle

00:03:05.563 --> 00:03:07.717
A wash bottle... There is one over there

00:03:07.978 --> 00:03:09.900
Oh shit

00:03:09.981 --> 00:03:12.341
Fuck, I got it all over myself!

00:03:12.371 --> 00:03:14.021
Hopefully, it was the water

00:03:15.979 --> 00:03:17.519
Aie it’s burning!

00:03:17.579 --> 00:03:19.239
It was not the water!

00:03:33.217 --> 00:03:37.039
Bad day in the lab

00:03:38.039 --> 00:03:41.469
