Easy Science Experiments For Children - Soda Balloon Experiment

[kmoorhead99]

Why doesn't the balloon pop?

[TheQuirkles]

@kmoorhead99 a balloon will only pop when it has been over inflated. We only used enough soda and salt to inflate the balloon.

Great for my kids. Very easy to perform.The hosts are very knowledgeable.

I recently watched this to my daughter and Wow! She now wants to see more of the Quirkles video

[joannafat0018]

Wow. My students will be happy doing this

[jetr0019]

Thank you so much Quirkles! Now , I understood how this really works

[gina57892]

Excellent! my students will learn so much with this

Can the balloon fly?

[TheQuirkles]

@Xwithouthim The balloon cannot float because it is full of carbon dioxide which is the same weight as the surrounding air. It would need to be lighter than air in order to float. Balloons filled with helium will float because helium is less dense than the surrounding air.

[Xwithouthim]

@TheQuirkles how do we make helium in a safe way then?

[TheQuirkles]

@Xwithouthim If you put helium in a balloon and let go of the balloon, the balloon rises until it pops. When it pops, the helium that escapes has no reason to stop -- it just keeps going and leaks out into space. Therefore, there is very little helium in the atmosphere at any given time.

[TheQuirkles]

@Xwithouthim

The helium that is in the atmosphere comes from alpha particles emitted by radioactive decay. In places that have a lot of uranium ore, natural gas tends to contain high concentrations of helium (up to 7 percent). This makes sense, since the decay of uranium emits lots of alpha particles and a natural gas pocket tends to be a sealed container underground. Helium is cryogenically distilled out of natural gas to produce the helium we put in balloons.

[TheQuirkles]

@Xwithouthim Helium is commercially extracted from natural gas. We don't recommend trying to do this yourself. Speak with a local professional that has experience with helium.

thanks a lot

[TheQuirkles]

@ahmadPLO21 No problem, thank you for asking! We hope you enjoy all the science experiments for kids that we have posted here on YouTube and over on The Quirkles website.

[ahmadPLO21]

can you explain what happened when the soda went up to the balloon please

[TheQuirkles]

@ahmadPLO21 Thanks for your question! The objective was to demonstrate the presence of carbon dioxide gas in soda. When we do the experiment we discover that the salt releases the carbon dioxide from the soda, making the balloon inflate. The more carbon dioxide the soda has, the bigger the balloon will get.

[ahmadPLO21]

great but can u explain how did u do it

[ahmadPLO21]

can u explain how u did it please

[ahmadPLO21]

can u explain how u did it please

[ahmadPLO21]

can u explain how u did it please :)

[handiest1]

Cute but you didn't explain the diferences....

[TheQuirkles]

@handiest1 Salt and sugar create nucleation sites, which cause a reaction with the carbon dioxide. There was actually very little difference in the inflation size of the balloon in this experiment. Any carbonated drink will work too.
