Fizzing and bubbling goop kids science

When playing around making our own scented goop  I came across this fun fizzing and bubbling science for the kids to try.

I mixed our goop up and then added a  kool-aid packet to it for a fun smell and it started fizzing and bubbling like a volcano.  It looked so cool and smelled so good.

We made rainbows, the kids explored color mixing, and made fireworks. They had alot of fun.

One of the best things about this science play is it is super inexpensive.

Cornstarch.....you can get this at Wal-Mart for $1.00 12oz
Baking soda....Wal-Mart as well 16oz for $2.00
Kool-aid packets....$0.20 at Wal-Mart
Tray or pan for the goop
Little containers for the kool-aid (optional) I had the kids use a little spoon to scoop the kool-aid powder onto the goop. (You only need to sprinkle a little bit at a time, but doesn't always happen with the kids.) 

How I made the goop:
2 cups of baking soda
1 cup of cornstarch
1/2 cup water

You can have it alittle runny or if you want it to be thicker add alittle cornstarch.

NOTE: You want to have more baking soda than cornstarch cause I think that is what makes the bubbling and fizzing due to the baking soda and the citric acid in the kool-aid packets when combined, but I am not a scientist. I just noticed when adding more baking soda to the goop on the tray it seemed to bubble and fizz more.

You can tell by "J" face expressions that it was fun and cool.

"C" she was so into it. As she was doing the colors I would tell her the colors of each one and have her repeat it cause we are working on colors with her.

We love doing fun science experiments, so be sure to check out some of our favorites below.
