Dear Readers,
Today I tried to experiment with my rainbow foam recipe. Instead of using water I decided that I wanted to see what would happen if I used Vinegar. Would it foam more if it is already foamy from the soap?
What happened was unexpected, but fun. To make it more Halloween like I decided to theme this sensory play around a Witches brew. The bowls held the potion (the foam) and I had some bone powder (baking soda) and eyeballs (cotton balls).
In a blender mix 1 cup of vinegar with 2 Tablespoons of dish soap and around 5 drops of food coloring. I added more because I thought it wasn’t enough, but as I will explain later start with 5 your first time… I added way too much. This is good for around 4 small cauldrons (the bowls) so if you wanted to do less, or make it more than one batch for other colors you could do that too.
When I mixed all the ingredients together the color just wasn’t showing. The potion was a really pale purple, an almost unnoticeable purple by the time I put 10 drops in. But I gave up.
I don’t know how well you can tell from the photo, but when you add your bone powder (baking soda) it brings out the color. By the time we were done with the potions my girls hands (and shirts) were purple too. Thankfully the purple wasn’t permanent.
I tried to contain the mess a little by using cookie trays or pans. While this worked for the most part, my girls wiped the potion on their shirts. This may not be too much a problem if you don’t use a lot of food coloring, but I would probably provide some protection for their clothes if I were you.
The girls loved it and it was a cool learning experiment for me too. I forgot to mention though that the potion did not fizz until it had settled from a foam into colored vinegar. Oh well, it still turned out pretty cool.
