Step 3: (Optional) Color the tree

If you like, you can add a little color to your shape by putting drops of food coloring on the edges. The food coloring will soak into the cardboard.
<p>Ace Hardware sells Mrs. Stewart's Bluing 8oz for $4 and will ship free to your local store.</p>
Why does it grow?<br>What chemicals are reacting? <br>Why does ammonia help it grow faster?
<p>If you look at step 7, mik3 explains it a little there. You can also Google &quot;how to grow crystals&quot; and find lots of stuff about it. You can grow crystals from other things too, like borax and Epsom salts. It's really fun and easy to do. </p>
Thanks it's because I have a science project coming up for school
<p>It&acute;s very hard to find the bluing in the UK. The only way is to order it from ebay and the shipping costs are quite expensive. I did some search and found this: RECKITT'S CROWN BLUE. Has anyone tried it before? Thanks, http://www.ebay.co.uk/itm/Bluing-for-Laundry-RECKITTS-CROWN-BLUE-4-PACK-Fresh-/251217742974?hash=item3a7dbe8c7e:g:KwcAAMXQCgpRvII7</p>
<p>I have never tried this, so I can't say for sure if it would work. I do know that you can grow salt crystals without using any kind of bluing. </p>
Did u try it yet
<p>Sorry, no. I had plans to do crystal growing, but I just haven't been able to do anything that I want to do lately. </p>
I found Mrs. Stewart's bluing at meijer's for $2.00 maybe because im in Chicago

<p>where you keep the tree? Ammonia is very stink in apartament. Where to put? Or how can i do this?</p>
<p>Do you know if using a Borax solution would work instead of the bluing solution? I am having a difficult time finding it? </p>
<p>You can grow crystals from borax very easily. The process is a little different and the crystals have a different structure, so they won't look like these. It is also possible to grow the salt crystals without using laundry bluing.</p>
I think you'll have the best results if you can find Mrs Stewart's Bluing. In the comments for another instructable (<a href="http://www.instructables.com/id/Salt-Crystal-Garden/" rel="nofollow">http://www.instructables.com/id/Salt-Crystal-Garden/</a>), they mention other kinds of bluing not working.<br> <br> You can try Amazon, or directly from&nbsp;<a href="http://mrsstewart.com/" rel="nofollow">http://mrsstewart.com/<br> <br> G</a>ood luck!
<p>These crystal trees are cute! I'm gonna make one as soon as I get the things to make it.</p>
<p>I remember doing this with my &quot;Mimi&quot;. (grand mother) I am now a Mimi and look forward to doing it with my grand children. I never would have found the recipe with out your &quot;ible&quot; probably wouldn't have thought to. so thank you. </p><p>Mimi </p>
<p>Nice . Thanks for posting this :)</p>
Two questions:<br>1) You said the ammonia was optional, depending on humidity, etc. I live in one of the rainiest cities in America so it's always very humid here, so would that make the ammonia more or less important?<br>2) If I wanted to make little kits as gifts, where I pre-mixed the solution and kept it in a bottle, do you know if it would keep and for how long?<br>Thanks! BTW, great instructable!
My Mom used to do this for us, when we lived in Seattle, back in the 1960's, and it worked fine-she always used ammonia.. We used charcoal briquets for the base then, but any thing that is somewhat porous will work for the crystals to grow on. Using briquets gave kind of a fairy-land look to the creation. Mom would put the briquets and solution in a pie plate, and let my sis and I put drops of liquid food color on the briqs to make the different colored areas, Magic to little kid! Just make sure they don't try to play in it! <br> <br>
I remember buying kits for my children, am looking for activities for my grandchildren over the holidays, this is definitely a good idea, thanks for sharing.
i just have a question, can you use horse bluing? the kind that makes them white?<br><br><br>thanks
So, it's a great instructable, undoubtly gonna try it. BUT, I'm from Denmark, and therefore I don't understand what &quot;Bluing&quot; is. Can you explain for a Dane?<br /> <br /> Thanks.
It's a additive used to make whites whiter in the laundry.&nbsp; It was quite popular years ago, but not widely used now.<br /> <br /> http://en.wikipedia.org/wiki/Bluing_%28fabric%29<br />
Uh, I see. Do you think chlorine could be a good alternative?
DO NOT EVER MIX BLEACH WITH AMMONIA~!!!@!!!! <br><br>If you don't believe it from me, then read this.<br>http://chemistry.about.com/od/toxicchemicals/a/Mixing-Bleach-And-Ammonia.htm
&nbsp;No, no, no! &nbsp;Ammonia tries to evaporate, and will carry the chlorine with it. &nbsp;I almost died once from breathing chlorine. &nbsp;Probably the worst way imaginable to die.&nbsp;<br /> <br /> Also, don't try bleach (another whitener), as mixing that with ammonia makes truly dangerous things. &nbsp;Read here: www.bbc.co.uk/dna/h2g2/classic/A795611
No, I wouldn't think so.<br />
Denmark!! Me too!! Well no my mom is, dad isn't, i'm half-and-half!
Oh my goodness I haven't done this in such a long time. My kids are going to love it. <br>Thanks so much for sharing it.
Does the bluing do anything, apart from colouring the salt? Would the project work without it?<br /> <br /> Thanks!<br />
the bluing is a colloid aka the crystal seed you need it to grow the crystals it otherwise is just a mix trust me it doesn't grow a thing.
This looks interesting but I'm not too sure I want to try this just yet. Maybe when my 4 year old it 5 or 6. She'll probably think it's candy from the coloring, lol. But I must admit that I think this would be a nice science experiment for my 13 yr old to give a try. <br>
Um...<br><br>It's bowl, not bowel.
Cool. I remember buying kits that we did this with as a kid in the 70's...Magic Grow or something like that. They really made a killing off of us kids, didn't they?
Would it work with any shape &quot;tree&quot; do you think?
It should work with any shape, but it's best as long as the material is porous ...<br> As a kid, we used charcoal briquettes, and there's another instructable that uses a toilet paper tube:&nbsp;<a href="http://www.instructables.com/id/Salt-Crystal-Garden/">http://www.instructables.com/id/Salt-Crystal-Garden/</a>
I think I just had a &quot;bowel&quot; movement here :)
Doh!<br> Hmmm, if I fix the instructable, nobody will know what you're talking about<br> ;-)
I see in the video that the crystals fall off sometimes. Any way to prevent?<br><br>Also, any scientific reason as to why this happens? Very interested in the process.
The crystals are pretty fragile, so when get too big they break &amp; fall off by themselves. Growing them in a place where they don't get jarred too much can help.
Do you think you might be able to use the cone styrofoam? The food dyes would certainly be absorbed. I will go ahead and try it unless you know why it would not. I will email you a picture of it if it turns out great. Thank you for the idea because I have grandkids that would it.
&nbsp;YEARS ago, my grandmother and I did this very same thing.<br /> We used pieces of brick. &nbsp;Made a little pile like a small mountain range.<br /> Then the ''forests'' grew!! &nbsp;Place drops of different colors of food coloring<br /> in different locations for a multi color effect
uuuhhhgggh!!? i need your help.? my tree is taking forever to grow, help me, did i do something wrong? HELP! its a goood idea thoughh(:<br />
Just though I would jump in here:&nbsp; If you are trying to find the Mrs. Stewarts Bluing - check this list of all the stores in Canada/USA that stock it!!<br /> <br /> http://www.mrsstewart.com/pages/wheretofind.htm<br />
my dear, just now I saw the picture of ammonia used here it is liquid, it isn't available here liquid it is powder, so can I use it?, if so liquid will be very little only 1 spoon water, salt and powder ammonia will not desolve well isn't it? reply me pls thanks
canadian nh....from another canuck...you can get liquid ammonia north of 49, but you may have to go to a janitorial supply&nbsp; store to get it without soap<br />
