Baking Soda and Vinegar

I’ve been meaning to let Bear {4 yrs} do this activity for awhile now. When I saw these sensory activities at 2 Big, 2 Little, I knew that we had to try it. I got the activity set up in about 3 minutes.  I grabbed the baking soda out of the fridge and poured the vinegar into 4 clean applesauce cups. I let Bear add the food coloring to the vinegar so that the colors would turn out like he wanted. He also dumped the baking soda on the tray and smoothed it out while I dug out the medicine dropper.  Using the medicine dropper in an activity like this provides practice for small motor skills and hand-eye coordination.

Bear didn’t need any instructions on what to do. Natural curiosity took over.

Sensory Activities

This is now one of our favorite sensory activities. Doing this in such small amounts creates a different dynamic than the baking soda/vinegar volcano experiment. It’s easier to see the actual reaction. Bear chose different colors and their placements, mixing colors at times.

Once most of the baking soda had been fizzed out by the vinegar, we added a bit more vinegar and mixed it up just to see what happened. The result was a really odd concoction. It was a liquid-like slime. Some of it was really runny, while the rest was thicker and chalky.

To take it a step further, we decided to explore this gooey substance.  Bear helped me scoop and pour it into a large Ziploc bag. Then we had fun squishing it with our feet.

This activity definitely put a new (and gooey) twist on a classic.  It’s one that we’ll definitely be doing again.

Baking Soda and Vinegar are at the top of the list of fun kids activities.  Check out these other ideas for using this dynamic duo:
