I can’t think of an eloquent word for the consistency that this creates. Paste? Slop? Sludge? It’s gooey and colorful and a little bit gross, which I think makes it perfect for young kids, always happy to stick their hands in goop.
This little activity is super simple and great entertainment for the kids. It’s messy, it’s fun, and my kids always love some good quality sensory play. As an added benefit, you can choose to do primary colors as an educational example of color blending.
A word of warning: this is an outdoor activity! Make sure that you immediately wash vinegar off of wood. I am a little embarrassed to admit that by letting my children do this inside on our table, I accidentally ruined the table by rushing them off to the bathtub rather than cleaning up first.
- Baking soda
- Food coloring or watercolors (food coloring may stain hands)
- Bowls and utensils for mixing
- (Optional) squirt bottles with vinegar water–careful where you do this!
1. In your bowls, add a cup or so of baking soda. You may use as many bowls/colors as you like.
2. Add water until it turns into a pasty consistency and stir together.
3. Add food coloring and stir.
4. Separate colors into containers. I did some stripes of color in a large Tupperware container for each kid.
5. Give them their squirt bottles and watch them have fun.
