What you need:
Freshly cut Queen Anne's Lace flowers
Food coloring (we used Easter egg dye)
Clear bottles
Water
Now, simply color the water (10-20 drops) and add a flower to each bottle. Then wait, keep checking the flowers every 10 minutes. Let them sit overnight too, they get brighter and bolder with time.
Make predictions about which one will be colored first. Orange was the fastest for us, then blue, yellow and green.The red and purple barely worked at all, the backs of the florets turned color, but you couldn't see it through the front.
How does it work?
Most plants "drink" water from the ground through their roots. The water travels up the stem of the plant into the leaves and flowers where it makes food. When a flower is cut, it no longer has it's roots, but the stem of the flower still "drinks" up the water and provides it to the leaves and flowers.
There are two things that combine to move water through plants -- TRANSPIRATION and COHESION. Water evaporating from the leaves, buds and petals (TRANSPIRATION) pulls water up the stem of the plant. This works in the same way as sucking on a straw. Water that evaporates from the leaves "pulls" other water behind it up to fill the space left by the evaporating water, but instead of your mouth providing the suction it is due to evaporating water. This can happen because water is very sticky--to itself (called water COHESION) and because the tubes in the plant stem are very small (in a part of the plant called the XYLEM). This process is called CAPILLARY ACTION. (Explantation from Steve Spangler Science).

We also tried this with Daisy Fleabane, the orange worked, but the rest of the flowers didn't change colors. Our next experiment will be to try and figure out why purple and red didn't work on the Queen Anne's Lace and why only the orange worked on the Daisy Fleabane.
Now I am off to press these beauties for a future activity! Enjoy!

So beautiful, all of it, the bottles of dye, the sprays of lace, just lovely! Warm wishes for a joyful holiday weekend!
think the kids will love to experiment with this.
BRILLIANT!! So fun. I've never been a big fan of fireworks. But this kind, I can totally get in to!! :-)
This is a fun idea and so perfect with the 4th right around the corner. xoxo
simply stunning!
cool, colorful, flowery, 4th of julyish, getting messy, fun, funny and pretty...
Those turned out great! You made a much bigger presentation out of it than I did. I just slapped a few pics up and said "hey, they did this." :D I'm glad your girls enjoyed it!
Those came out great-thanks for the scientific explanation too!
We used to that at my grandma's house--Benjamin & I just visited her grave today, so your post has made me a bit teary-eyed.
Benjamin left a tiny pine cone and two acorns on her gravestone--it was just precious.
Thanks for this post--it made me both smile & want to cry. :)
Wow! Thanks for the great idea. I'm going to try this with my kids next week. :)
Fabulous!! We are doing this tomorrow!!
This is amazing, yet again. Not surprising from you. Can't wait to try this. We made popsicles today inspired by your previous post.
Now I have something cool to do with my overrun yard full of Queen Anne's Lace!! Thanks!
Looks Sooooo pretty! Just like fireworks!
Oh! I so need to do this, what an incredibly cool idea!
What a great idea! I've never tried this with flowers - I can't wait to find out why not all of the colors worked. Hmmm...
That looks so pretty - I imagine a child would be utterly entranced by the transformation that takes place with it.
Oh, and I adore Queen Anne's Lace - it has such a gorgeous, delicate, summery old world vibe.
thank you for this colorful idea. my son will love it. i'm sure. wish you a sunny day*
Beautiful and poetic idea !!! I'll try !
Such dramatic results with this!
The science is pretty cool too.
These are beautiful!
Ooh so pretty. I seriously want to try this now. I can't wait to look at your blogs when I have kids!
we've only done this with celery and carnations. Your version is a million times more beautiful, especially with the rainbow of colored water. Have a happy 4th!
Wow! Beautiful!!!
wonderful project! we will be doing this for sure, thanks!
I first did this 40 years ago with my Grandma and only thought to do it for the first time with my daughters last summer. We left all the colors sit for 3-4 days. The purple got a nice pale shade after that amount of time, but the red had only a slight pink tinge. We don't have any QA's LAce blooming here yet, but I am looking forward to doing it again this summer.

I used to love doing this when I was a kid. I never thought to do it with any other flower but daisies or roses though. I also really appreciate the scientific explanation behind it too. I remember learning about cohesion and adhesion in my very favorite college class. It was life science for el. ed. teachers. We have a firework flower in our garden at home. Since I'm not there to take a picture, here's a link.

PS. Looks like you have a fetish for glass bottles and jars like I do!
what a fun idea, I will try this summer for sure !!!
Great post, and beautiful pictures! My son has been asking to dye flowers this way, after he read about it in a book. i didn't think we had any flowers it would work with...but we have queen ann's lace! Wohoo! He will be thrilled. :)
