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
After you make the goop then you sprinkle kool-aid powder on it and that is when you get the bubbling and fizzing science fun.
NOTE: You want to have more baking soda then cornstarch cause the bubbling and fizzing happens due to the baking soda and the citric acid in the kool-aid packets when combined. 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.
