Tons of demos and experiments but how to share?
I have been digging through my boxes and boxes of books and other chemistry stuff and came across something I forgot i had!
Its a collection of chemistry demos and experiments from 1924 and later, the book itself is over 250 pages of compressed text, just solid blocks of
amazing demos, one after the other. The safety precautions are definitely light and very old style. Nothing like you would see for demos in modern
chemistry manuals.
A collection of "Tested Demonstrations in Chemistry". Has lots of experiments I have never heard of or known of but that seem very cool including
chemiluminescence, one of the ingredients is cayenne pepper!! (I havent tried it but its in there)
My problem is here: The book is bound with huge staples that I can easily remove and glue on the spine. I will try and scan it all into one document
if there is enough interest from you guys... It feels like a waste to not share the amount of cool stuff in this collection! If this is a fairly
common book I wont bother but I cant seem to find any copies online...
Worse comes to worse if anyone wants old fashioned experiments on certain elements, reactions, mixtures, let me know and I will scan the pages on that
topic and post them  There is something for everyone
I threw a few photos of the pages, some are compressed text with instructions for one demo after another and others have more complex diagrams and
whatnot. A very cool book!
Does anyone know an easy way to scan and assemble the pages in order easily?

That book looks fabulous!
Most cameras these days will have sufficient resolution to produce readable images. Even with the low resultion images posted, it looks as if yours
will do the trick, so with a simple stand and higher resolution you should get decent results.
The diy bookscanner web site would be a good place to start: http://www.diybookscanner.org
There's open source software called Scan Tailor for tidying up pictures, deskewing etc. that's worth investigating: http://scantailor.sourceforge.net
But if it's only held together with staples, disbinding and a flatbed scanner might be the best way to go.

That book looks familiar to me somehow. DId it have a light blue cover do you know? In the book is there was experiment called purple rain in which it
said it was no longer recommended.

i love older books like this one! i have a collection of them from 1876 to present most of them from the early 1900 and the 50's.
cant find anything quite like this anymore! always a good find! treasure it keep it safe away from humidity..... and kids!!

Thanks for the suggestions malcolmf! Sadly I took a closer look at the binding and despite the book being bound in huge staples it is also made up of
about 15 "mini-books" so after removing the staples I would need to actually cut the spines off with an x-acto knife and then scan them normally etc.
After the whole affair is done, knowing my excellent organizational skills when it comes to keeping papers in order.... it would be the end of the
book. The pictures there were just taken with my iPhone 4 and it usually makes good pictures of print. The idea crossed me to set up a stand with
clamp over the book and then turn the pages one by one and photograph them. That would work pretty good except that the iPhone creates huge photo
files (2-3 mb each) and doesnt give the option to reduce quality. Meaning I would not only need to attach each image separately and assemble them with
software, I would also need to reduce the file size for each one.. Just seems like too much work.
Maybe on some rainy day I will commit to trying along with having a few beers 
The book did have a blue cover which fell off when I took it out of storage, not a big loss though... didnt even say anything on it.
The purple rain experiment you mention sounds interesting especially since even THEY said it wasnt recommended... must mean it was something good!
Another drawback to this book is the fact that there is no list of the names of demos, just topics like : Plastics, Platinum family, Poisonous gasses,
Pyrophoric materials etc etc
Nothing mentioned for purple rain though, I checked precipitates and there was nothing. I plan on going through the book page by page and putting
those sticky tabs on all the ones that I find interesting and that have things I want to try. The last time I opened this book I had nowhere near the
reagent selection I do now so lots more things will be possible
I do love the older books too neptunium! The style of writing is different, safety considerations are at minimum but still not dangeous if one uses
common sense and keeps the feeble warnings in mind lol
When I come across cool pages ill upload them individually to shareif theyre worthy of it, and again, if anybody wants demos on a certain aspect or
topic of chemistry, let me know and I will share everything on the subject

The purple rain demo was more of an explosion and it cited a few detailed accidents when being demonstrated, ending in a caution the experiment was no
longer recommended. It was a KMNO4 demo I think.

Ah, okay.. Just checked and the index lists about 20 pages with "explosion" demos so I will check and see if I can find the details later
I did find a demo that instructs each student group to place a pile of sodium peroxide on some tissue papers and to use squirt guns to spray the
peroxide and "witness the violent reaction" ... it later mentions to be careful for skin and eyes when doing this due to "spray, mist and particles"
hahaha!

If that is the book I am thinking of there is another unintentional explosion where two uncommon sounding liquid chemicals were mixed together and
then exploded 5 or 10 minutes later, something like that with glass flying and perhaps some minor injury. Fortunately the person had walked away from
where the flask was resting. It was unsuspected that these two liquids would form an explosive. Again, they were odd compounds if I recall. It's been
so long I could be mistaken about the details of the explosion or have it confused with the purple rain accidents.

Sweet. We definitely need more experimental procedures that include the use of cow blood.
Just those pages you posted were a hoot. The whole book would be a great read.
I would suggest doing just a few pages at a time. A maximum of, say, ten. And converting the scanned pages into Word by using Abbyy Finereader or
something similar.

Tested Demonstrations in Chemistry
Okay so here is a first try at creating a Word document and using a flat-bed scanner, thanks for the idea btw!
Instead of driving myself mental and trying to scan the whole book all in one go, I will add 5 mini chapters every few days to the document, probably
a lot more if I have free time.
The cover page had to be omitted as well as the last page of the Hydrogen section because of file size limitations.. this is where my problem is. My
scanner usually makes a scan at low quality at about 1 mb, my current method of reducing file size brings them down to about 250-300k ea. Anything
smaller causes a serious degradation of quality and loss of readability.
That means that the current document is just below the forums 2mb upload, this also means that the whole document would be over 300mb at my current
rate. This is my problem... I dont mind scanning page by page manually, but the file size is an issue that i cant figure out. How can I make a
word/PDF file that contains all pages and stays within an acceptable size? I could always use external file hosting I suppose, until it is complete
and of acceptable quality to be added to the SciMad library.
Anyways, the first parts of the book are basic experiments on oxygen and hydrogen, my next scan will add (provided I can fix my scan and file size
issues):
-
-Water, Acids, Bases and Salts
-States of Matter: Solutions
-Ionization
-Energy
-Equilibrium/ReDox
-Atomic Strcture: Radioactivity
-Group Zero (inert gases) and The Atmosphere

You are doing this the hard way, saving scans in Word as graphics. What I was suggesting is that you use Abbyy or some other OCR to scan and convert
to actual text in Word. Then the results will be hugely smaller and be searchable and indexable.

Scanners now have software that make multi page tifs and pdfs

Thanks for the help! My job provided me with a copy of acrobat which allows me to scan directly to pdf, so much easier! I will replace the word file
with the pdf once it is started.

You could always scan the whole book into a PDF file, upload to a website like mediafire, and post the link here, effectively bypassing the forum file
size restrictions.
I myself am really intrigued by this book. Many of the old books are the most interesting to read, "Golden Book of Chemistry Experiments" to name one.

I have actually been scanning pages daily, im about halfway through at the moment. I decided to convert it all into a pdf with Acrobat... Its just
taking a little while but it should be complete by end of month!
Originally i was going to add a few pages every so often and update the document but I think it would be much easier and much more interesting to wait
for the entire book to be done and that way everyone has a full copy.

I cant wait for this, the few pages I saw really have me wanting the rest.
Releasing the book as a whole is pretty good idea, that way nobody ends up with a partial copy, scouring the Internets for the rest. Should be quite a
good read once it gets out.
Really appreciate what you are doing for the community by the way.

Is there a problem with the copyright on this book? That is, would it be a copyright violation to scan the book and post it as a pdf?
I don't know what the relevant laws are, but the book is almost 50 years old.
Any other SF Bay chemists?

I have no clue. It's an old collection of journals so I'm not certain. The SM library has lots of books scanned to PDF and it doesn't seem to cause
much of a fuss, I'm not overly worried though.

New Clock Reaction/ Preparation of Dicinnamalacetone!
The scanning of this book is taking much longer than I thought, been busy..
I did come across this experiment on the weekend, tried it with nice results with cinnamaldehyde.
Thought I would share it

Sorry I haven;t updated this in a long time, it's time consuming to scan a book and hard to find time to do it. I did some of the photographic
chemistry demos and thought they were worthy of sharing though.
Recipes for all sorts of photographic formulations are given and experiments with the solutions also provided. Was fun!
Unfortunately my scanner makes images too large for the forum to accept, so I had to compress each scan\page into a zip file. One page has a bit of
blurring where the spine of the book is but no information is lost.

I believe that book is a compilation of articles that appeared in JCE. I think that anyone who is a member of ACS can access pdf versions of the
original articles from the ACS website. I assume we have some ACS members here...

Sweet! Thanks! In the meantime if anyone has a specific topic of interest, let me know and I don't mind scanning some requested pages/topics

Well it looks like scanning that book never happened due to lack of time and motivation  I did however come across this online. Quite a few neat things in there, the first page has an interesting demo with an activated cobalt complex.
