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
-
bottle and pour in your vinegar.
-
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.
-
And you should get… a BALLOON BLOWOUT!
-
To find out why the balloon inflates, head to the
-
Questacon Science Squad website. See you next time.
