We posted a picture a few weeks ago with baking soda and vinegar. We had a few questions on how it worked and what you do. Here is the science behind it...
"Baking soda is the chemical called sodium bicarbonate. Vinegar's main
chemical component is acetic acid. The ions formed when the baking soda is
dissolved in water react with the ions from the acetic acid to form carbonic
acid, which quickly reacts, or decomposes, to form carbon dioxide and water.
The bubbles from the reaction are the visible evidence of the carbon dioxide
escaping from the solution as a gas. The remaining solution is sodium carbonate
and water." ~ Sophisticated Edge
This is something extremely simple and can be done with stuff you most likely have on hand... Baking Soda and Vinegar.
Here are 9 different ways we have played:
Baking Soda in a cup with a little bit of food coloring or liquid water colors. Squeeze on vinegar.
The reaction!
Vinegar in a tall vase. Test tubes would also work great. Pour on baking soda. You could also switch the two around.
You can do this one in the sensory box to contain the "mess".
Vinegar in a container... shake on baking soda.
Baking soda in an egg carton. Drop on color and vinegar.

That looks like fun! What great ideas.

I've heard that food coloring stains, but I can't find any good info on liquid water colors. Do they stain concrete?
ReplyDeleteSo cool, i love doing things like this with my 4 children, makes my science degrees not so useless!! Love Posie
ReplyDeleteMake sure the vinegar doesn't get in the kid's eyes. It is extremely painful. Might want to put a note at the top.
