What happens if the balloon doesn't inflate?

Ensure the baking soda and vinegar are fresh, as expired products may not react well. Also, check that the neck of the balloon is securely placed over the bottle.

Can we reuse the balloons?

Once the balloons have been inflated for this experiment, they may not hold air for long; consider this a one-time fun craft.

Will the reaction damage surfaces?

While the mixture is generally safe, it’s best to work on a surface that's easy to clean, like a table covered with newspaper or a plastic sheet.

What other crafts can we do with balloons?

For more balloon fun, explore projects like rainbow tissue paper flower lanterns or these clear rainbow ghost shaker suncatchers!

How do we safely dispose of the materials?

You can simply throw away the used balloons and leftover mixtures; it’s biodegradable but always check local disposal regulations.
