fizzy apple painting

Our last apple project for the season was fizzy painting on apple templates. The basic idea is to paint the shapes with baking soda paint and then paint over them again with colored vinegar, to create the chemical reaction and “fizzes” on the paper. We used yellow baking soda paste (just baking soda and water, mixed to a spreadable consistency) and red and blue vinegar, so that in addition to the chemical reaction the boys could see the principles of color mixing. Finally, the website I’d found the idea on suggested that the shapes could be cut out and used for fall decorations after the fact (and their apples did look quite nice!), either on a garland or as sun catchers in a window. So there were a lot of different facets to this project.

Rondel demonstrating various phases of the process, from painting to taste-testing (just a heads-up that while baking soda and vinegar are completely edible, they may not cause the most pleasant reaction in your stomach if you eat too much, as Rondel discovered the hard way):

The baking soda paste was difficult to paint with using our foam brushes – it may work better with standard brushes, but I don’t have any of those yet for the boys. The vinegar went on pretty easily, although we did end up spilling a lot of it when one of the bowls was knocked over!

Both boys noticed that orange and green somehow appeared on the papers despite not being in any of the paint bowls, but they were far more captivated by the fizzing. At some point, they realized that they could make the whole bowl of vinegar paint fizz up by dipping a brush covered in baking soda paint into it, and they were both delighted and fascinated.

In fact, Rondel went so far as to mix all the paints together at the end, just to make the biggest fizzy reaction possible!

Limerick was too distracted by his paintbrush to notice. though…

While it wasn’t the longest activity, because we ran out of paint fairly quickly, it was a novel and exciting one; both boys asked me to make more paint when it was done, actually, which was a first for a “crafty” sort of activity. Maybe I just hadn’t made enough, since I had made way too much paint for our last craft, but I think their smiles attest to the success of the project even though the apple paintings themselves ended up in the garbage can:

I think I’ll need to plan another fizzing activity, though! I’ve already found a pumpkin one that holds some promise so we’ll see how that goes πŸ™‚
