We recently experimented with baking soda and vinegar and did some really fun activities! I’m excited to share these 5 experiments with you today.
To start off, just pour some baking soda in the bottom of a container. We used this hourglass from Gummylump because it’s a fun container. Slowly pour the vinegar in. Watch how the two react and eventually bubble over the top! This activity is good for practicing life skills of pouring.
2. Jumping Seeds
Dissolve 2/3 teaspoon of baking soda in 1/2 cup of water in a large glass. Add apple seeds from a couple apples into the liquid. Then add 1 tablespoon of lemon juice and stir the mixture. The bubbles will carry the seeds up and down. It is really neat to watch! Here’s a short video of the seeds ‘jumping’!
First, place a vase on a pan. Add playdough around the vase to make it look like a volcano. Make sure you use playdough you don’t want anymore, since it will be ruined after the experiment. Pour baking soda into the vase. Add food coloring (optional). Next, add the vinegar to the mix.
4. Blow Up a Balloon
Use a funnel to pour vinegar into a plastic bottle.
Place a balloon around the funnel and fill it with 2 teaspoons of baking soda. (This next photo is real life…tears from our toddler because he didn’t want to wait his turn…)
Side note: you may notice the last photo is a different bottle. We tried this experiment with a smaller bottle and the balloon blew up bigger than than with the larger bottle. Also, you could experiment with more baking soda and vinegar to make it blow up even larger.
5. Vinegar Ice
To begin, fill an ice tray with vinegar and add food coloring (I used a star mold). After it’s frozen, pop them out and place on a plate. Pour baking soda on top and watch how the ice reacts to the baking soda. To speed up the reaction, pour vinegar on top. It’s a fizzy mess!
