Balloon Experiment in a Glass Bottle

This coloring page features an exciting and classic science experiment that can easily be recreated at home or in the classroom. In the center of the image, there is a simple glass bottle. A large, round balloon is stretched securely over the mouth of the bottle. At the bottom of the bottle, you can see an uneven layer of a powdered substance, likely baking soda, with tiny bubbles rising up from it. These little bubbles indicate that a chemical reaction is taking place right now, producing an invisible gas that is slowly inflating the balloon above.

A great science motif to color

The large, continuous areas of this coloring template make it particularly easy to fill with color. Because of its simple shapes and clear outlines, this picture is perfectly suited for younger children from about three or four years of age. The large balloon offers plenty of space to get creative. You can choose a single bright color, or decorate it with your own stripes, polka dots, and fun patterns. The glass bottle can be colored with a soft light blue or light gray to make it look like real glass. The rising bubbles can be highlighted in a bright yellow or left white.

Interesting facts about the experiment

The Chemical Reaction

When you mix baking soda and vinegar together, it creates a gas called carbon dioxide.

The Magic Effect

Because the gas needs more space than the liquid, it rises upwards and fills the balloon, causing it to magically inflate all by itself.

Fun ideas for little scientists

• Color the large balloon in your absolute favorite bright color.
• Draw a small table, a lab bench, or a work surface underneath the glass bottle.
• Color the reacting powder at the bottom of the bottle in a light ochre or sandy shade.
• Count the tiny bubbles in the bottle and color each one slightly differently.
