Expanding Balloon Science Experiment

May 18, 2026 by Annette Kaminsky Leave a Comment

This super-easy expanding balloon science experiment includes balloons and two basic household staples, which is a win-win combination. The bubbly experiment is perfect for all ages, and children can easily help with the activity.

_______

Supplies to Collect

To perform this fantastic chemistry experiment, gather the following inexpensive supplies:

white vinegar
baking soda
large balloon
water or juice bottle
measuring cup (optional)
measuring spoon
funnel

The Expanding Balloon Science Experiment

In this fizzy science activity, start by stretching a large balloon and blowing a little air into it.

Next, let the air out and place a funnel inside the rolled edge. Spoon in three teaspoons of baking soda. If the bottle you will use is on the larger side, use heaping teaspoons of the powder. Shake the balloon a bit to get the baking soda to the bottom.

_______

Then pour vinegar into a clean water or juice bottle and fill it about ¼ to 1/3 of the way. Pour the vinegar into a measuring cup first to make this step easier.

Afterward, carefully fit the balloon snugly over the mouth of the bottle. Keep the balloon hanging off the side as you do this.

_______

Lastly, lift the balloon so the baking soda drops into the bottle and watch the two ingredients bubble and fizz as they react. The balloon will magically self-inflate.

_______

The Science Behind This Balloon Experiment

Vinegar is a liquid, and baking soda is a solid. In this bubbly, fizzing science experiment, there is a chemical reaction between the vinegar (an acid) and the baking soda (a base). As the two ingredients interact, they release carbon dioxide gas. The gas expands and goes up the balloon, causing it to inflate.

_______

Variations of the Expanding Balloon Science Experiment

To extend this magical science activity, try using different-sized bottles and varying amounts of vinegar and baking soda to see if the experiment works out just as well.

_______

To make the eye-appealing activity even more colorful, add food coloring to the vinegar in the bottle and use a clear balloon.

Fall Forest Sensory Bin

November 30, 2025 by Annette Kaminsky Leave a Comment

This fall forest sensory bin is inspired by a tiny mouse that snuck indoors. The unexpected discovery led to the question: “Can mice survive outdoors in the fall as the weather turns colder?” The answer is “yes”!

_______

Although mice will happily seek shelter indoors when the weather cools, they are perfectly capable of surviving outside during the fall and winter months. In the forest, they build nests in sheltered spots such as logs, under tree roots, and underground burrows. They also dig elaborate condo-like tunnels underground, with a pantry, bedroom, living room, and latrine.

_______

In autumn, the quick little rodents get very busy finding nuts, seeds, and berries to store for winter. This involves many trips to and from food sources. Along with growing thicker fur, the focused, energetic activity helps keep them warm.

This leafy sensory bin with soft late fall hues features a bunch of scurrying mice in a forest environment.

Three Dinosaur Sensory Bins

September 7, 2025 by Annette Kaminsky Leave a Comment

Dinosaurs are an oh so popular topic among young children, and they absolutely LOVE sensory bins. This post combines the two interests. featuring three dinosaur sensory bins that are bound to captivate your little learners. A bonus is that the activities are super simple and quick to set up.

_______

Children adore anything dinosaur, so I try to include dinosaur activities in my yearly rotation of themes. It’s not hard to do, as there are thousands of activities to choose from.

Sensory activities are also a favorite of children and offer a host of benefits. They provide multi-sensory learning through play experiences.

_______

Dinosaur Rice Bin

_______

The sensory bin for this first activity is a white kitchen bus tub, which accommodates two or three children at a time. If you’ve seen some of my other sensory blog posts, you’ll know that this is one of my favorite choices for bins. An under-the-bed storage tub also works fantastically. It is slightly bigger in size and accommodates more children.

Rice is an economical sensory base and is reusable. Brown rice is the base for this first sensory bin.

Other supplies in the bin include:

large and small dinosaur figurines
glow in the dark dinosaur skeletons
dinosaur skull figurines
marbles
fillable eggs

Exploring rice is a calming activity, and children love to pour it, bury items in it, and create shaker musical instruments using it as a filler.

_______

In addition to adding rice to the fillable eggs, children eagerly hide smaller dinosaurs and marbles in them.

Larger dinosaur figurines, dinosaur skulls, and glow-in-the-dark dinosaurs contribute to the theme and add excitement to the bin.

_______

_______

Dinosaur Egg Rice Bin

This second dinosaur sensory bin is simpler and features a few variations.

_______

White glutinous rice is the base. Its bright white color helps the accessories stand out.

An edged, square metal serving tray is the bin. It is smaller in size than a kitchen bus tub, accommodating one to two children at a time.

_______

Fillable eggs with dinosaur spikes were the inspiration for this bin, and are a feature supply.

Various sizes of rocks are natural materials in the bin.

_______

Dinosaur Noodle Bin

_______

This third sensory invitation is similar to the one above. The only difference is that the base in the bin is thin, yellow noodles. The bright, cut uncooked noodles add a pop of color and novel texture to the bin.

_______

Benefits of the Dinosaur Sensory Bins

Sensory bin invitations are non-threatening, open-ended activities for children to participate in. There is no right or wrong way to explore them, and that means zero pressure to meet certain standards.

The rice in the first two bins is relaxing for children to touch, sift, and pour. This helps children regulate their emotions.

As children add little dinosaur figurines and marbles to the fillable eggs, they gain hand-eye coordination and fine motor control.

Children take delight in making shaker musical instruments by adding rice to the eggs. This includes a musical component.

When two or more children play in the same bin, they practice sharing and turn-taking. Their discussions during the play enhance social development.

The sensory invitations have a collection of unique accessories that are new to the children. This encourages the little learners to be creative and use their imagination.
