A nice round red/purple cabbage...
Chop it up!
Boil in water (with lid on; lid off here for photo!)
Strain cabbage; you can eat the cabbage or boil separately for borscht soup or a veg stew! We had ours with noodles in miso soup :-), and then a 2nd batch with toasted sesame seeds.
Find a nice tray & pour the cabbage juice into it. Using tongs, dip your paper into the purple juice.
Swirl it around! Remember to wear your apron!
It can really stain (see above)
Hang your piece of paper to dry!
Remember to place an old rug underneath
When they're dry, you're ready to paint with non-toxic paint:
a) diluted vinegar & water - turns the paper pink
b) baking soda & water - turns the paper green
It's also a good time to explain to older kids the chemistry behind it all!
My son went crazy and soaked the whole sheet !
This is the result. We'll be using this for our next home project!
