Science Rocks! Baking soda and vinegar activity

SuperSam has been all about doing experiments lately. He likes to wake up early from afternoon nap (before The Sisters are up) and use the time to do “Science Stuff.” It’s nice for us to be able to spend some time one-on-one, and it gives him a chance to feel like he is doing Big Kid Things. Usually, he spends at least part of the time talking about how this activity (whatever it is) “wouldn’t be appropriate for The Sisters.”

He loves that word, appropriate.
I am probably to blame for that.
Anyway. I set up a baking dish for him with cups of vinegar (one with blue and one with yellow food coloring added), an eyedropper and a dish of baking soda. I didn’t give him any further instructions.
He started out slowly.
With the first fizzy reaction, he got really excited and fell off his stool. Fortunately, he wasn’t hurt and went right back to work.
Soon, the eyedropper wasn’t making things happen fast enough for him. I gave him a syringe. Then things got wild. He started making sound effects as he squirted the vinegar.
An unsuspecting Tyrannosaurus who happened to be hanging out nearby was pulled into the action.
Finally, SuperSam abandoned the syringe completely, dumped everything in together, and turned it into a sensory activity with a side of process art.
This activity is easy to set up, easy to clean up, and lots of fun to watch. I’m definitely adding this to our official List of Things to Do When We Need SuperSam to Stay Busily Occupied for about 20 Minutes Or So.
Have you done this activity? How did it go? I’d love to know if you try it.
