Blueberries, turmeric, and kale/spinach mixture. Yep, we boiled all three..added a little vinegar and success! Well, full disclosure–we added green food coloring to the kale/spinach mixture because it just wasn’t cutting it. But overall, we had a fun time with our little science experiment in the kitchen, and the kids were happy with their results! We’ll try this again next year for sure.
