Baking Soda and Vinegar Bubbles

I'm sure most of you have heard of science experiments such as making volcanos with baking soda and vinegar.  Well, our daughter loves this little activity and will work at it for quite a long time without getting bored.  We call it "bubbles."

Just put some baking soda in a dish or tray.
Drop some food coloring in small bowls with vinegar.
Combine the two any way you'd like, and enjoy the fizzy bubbles!
We use spoons to drop the vinegar into the baking soda but a medicine dropper would work too (that was a little bit too complicated for us to figure out how to use at this age).
Beware that if you put the baking soda into the bowl of vinegar instead of the other way around, your fizzy bubbles will be totally fantastic but will most certainly overflow so be ready for a mess!

After a while, when the baking soda is totally saturated, the bubbles no longer work but then we have a great dish full of goopy yuckiness that is perfect for pretend cooking so we usually break out some measuring cups and extra water to finish up our play.

Have fun!
