Materials: water, white vinegar, food dye, tall plastic Indian-food containers
Explanatory details: we made red, yellow, and blue from the dyes and then poured and mixed to make orange, green, and purple.
How did it go: Great! Junie was very interested in the dye mixing and eager to put eggs in there. Using the Indian-food containers worked very well as they were tall enough (over 2x the depth of the dye) that splashes were contained when she dropped the eggs in. I had put too much red dye in the red so both the orange and purple were basically also red; we probably would have gotten better results by making each color individually from the food colors, rather than mixing the made-up primaries, but this is Science for Tinies, not Art for Tinies, so whatever.
Things we talked about: I tried to get her to guess what color would result from each mixing but she was reluctant to guess, so we just talked about what we saw, both in the liquid and in the color of the eggs that came out.
What Junie got out of it: I asked her just now what she liked about it and she said "green!" and "Trina made purple!"
