Yes you have to but here is a tip: if you want the sturdiest balloon blow it up halfway and then insert pancakes before you blow it up anymore
Yes, because your breath is warm.
Really?
A balloon can't blow itself up - it can only respond to internal and external forces. For example, if the pressure inside the balloon is greater than the pressure outside the balloon, it will inflate; if the pressure is greater than the balloon is able to stretch, it blows up. Balloons that are filled on the ground, for example, and then released into the sky may eventually blow up as they reach altitudes with lower air pressure.
Either.
When the gas particles hit the walls they blow up a balloon

the balloon that will blow up the biggest is sprite as it is more fizzer and will be big.
Making cookies would constitute a chemical change.
No a cow will not trust you if you blow up its nose! What kind of question is that????!!!!!
That is a very strange question. Blow up like a balloon-no. Explode and shoot guts all over you-yes if you hold its mouth, nose, eyes, and butt shut and if you blow hard enough (Ask a weird question, get a weird answer)
No
An older kid should be able t blow a bigger balloon because a younger kid would have less breath and would therefore blow the balloon up slower and the older kid would be able to blow the bigger one. Also, the more air in the balloon the harder it will be to blow it up.
Yes it can, the chemical reaction creates co2 which will go in the balloon therefore it will blow up.
You normally blow a balloon by using your mouth and emptying the air out of it into the balloon. Or buy a pumper from party city.
