Sharpie Dye Color Bursts

[BLucy]

Both Vis-a-vis and Flair markers work well using water instead of alcohol.  I've done it with quite a few different groups of kids and they all get into it.  Some of the markers will separate into different colors, especially black.  Coffee filters are fairly cheap and the kids try out all kinds of things from solid coloring, to just dots or line designs.  It's a great project, and the spray bottle works really well.

This looks so neat!  Definitely going to try it!

takes you a link with a video, it was neat to see it in action without trying it first!

This is cool. Now I've got something to do with some of my sons old white tshirts.

Thanks for sharing!  I think that would be great for quilt centres.  So when heat set, it is supposed to be permanent?  I wonder what would happen with the glittery permanent markers, or the metallic ones.  Or on wool.

Those are beautiful! Thanks for sharing!

My son and I made several of these last night.  I used t-shirts and scraps of white fabric.  I won't hijack your thread with our pics of them, but they came out super great!

My son is five and he REALLY enjoyed this project!

IamSusie, I was thinking this would make neat quilt blocks too

The quilt making pressure!  I agree!  I must make a quilt from these blocks. I also should do some washability tests for you guys.

I do not care in the least about "hijackings".  Post the pics!  or link us to your own post about them!

This is so incredibly cool!  I want to try it out soon!

This is really cool! Think I will have my boys do it! Then take the squares and make them into a quilt!

Wow.  I am a new quilter, but not a new scientist.  We used to do these in physical science and chemistry (ex teacher here) and it was great to see the students' designs.  Some even ended up as hangings in the classroom.  We also only did them on filter paper rather than fabric.  I definitely have to try this some time myself now that I am a quilter.  I remember that we had several brands of markers that worked, and several that didn't. 

I love color chromatography!

Also we investigated the different black brands of markers.  A lot of black markers had purples in them, and some had green. 

I have started a new blog/podcast about science in quilting, do you mind if I link back here sometime?  This is like perfect. Exactly the type of projects I was thinking about when I made my blog! (http://scientificquilter.wordpress.com)

Good for you for doing this and posting it.  Thanks to all the other posters here who have added things they know about the types of alcohol to use, how much and the spray bottle tip, awesome!

Has anyone tried the opposite?  Make an outline with different color markers and drop the alcohol on the outside, so the markers shade into the center and "color" the middle of the design?
