What you will need:
1. 1 bag of ice (cubes preferable) I also noted you can do this with snow too!
2. Various dyes. I used Jacquard and greener shades for our experiment.
3. silk scarves (you can use anything that will take dye. (It might be neat to use with technique with braids of top?)
4. Catch tubs or buckets to catch the dripping dye.
5. Trays with openings with enough to allow the dye to flow through.
Get your dyes and get creative. My son grouped a few colorways together for me to use. So I followed his lead an began adding dye from an eyedropper. I also tried sprinkling the dry dye as well. I tried to add different levels of dye density, but ultimately the melting ice dictates the flow of the dye, and that's probably why the results are so dramatic.
After we did 4 scarves we were done and about 20 minutes later the wind came up and took one of the scarves. I grabbed it and it was totally, dry so I rinsed it in the sink and added a little soap to get out the vinegar scent then hung it out to dry.
Later, I made a couple of nuno scarves. They really have a wonderful flavor from the ice dying. I had a lot of fun and so did my 5 year old!
