Hi, my name’s Steve and I’m from the Questacon Science Squad. Today I’m going

to show you how you can inflate a balloon even if you’re a bit out of breath.

What you’ll need is a 600mL plastic bottle, a funnel, a teaspoon, some

bicarbonate of soda (or baking soda) and about 150mL of white vinegar.

First what you’ll need to do is get the funnel and insert it into the neck

of your balloon. Then get your teaspoon and put in two heaped teaspoons

of baking soda into your balloon and make sure you shake it so

that all the baking soda goes to the bottom of the balloon.

Next, get your funnel, put it in to the top of the

Now we’re going to get the neck of our balloon, stretch it over

the top of the bottle so that it’s on securely.

Now you want to hold onto the bottom of your bottle really tightly and tip up your balloon

so that all of the baking soda goes into the vinegar.

To find out why the balloon inflates, head to the

Questacon Science Squad website. See you next time.
