WOW! I need them too. My teacher assigned so much homework and projects. So i need lots of help. THANK YOU! (if you do)
😂😂😂😂👍
Sir, My son longs to have you as his science teacher... You are the best.. Congratulations
?

Your videos and explanations are great. Thank you! Please keep making them!
Jared, these videos are great. I have been teaching science for 40 years and your presentation is FUN! Thank you!!
Wow, thanks! Bruce.....we appreciate the support. the FSD team
Thanks for spreading science!
This is just great...so well explained. Kids just love doing this particular experiment themselves. Well done.
Thanks,
You are very good at explaining things and helped me to understand air pressure
Thank you so much !! I have a review package due for my air and aerodynamics unit, this helped so much ✏️
Thank you for doing this! It helps me in science!
without any doubts the best channel on science experiments on You Tube, Jared I enjoy very much the way you explain amazing things about life with just a few things

I love your experiment
It's amazing!🤗🤗
Just amazing. Thank you so much
For the first time I saw your video and you are awesome
good explanation...
very good to learn
It is very interesting
This is amazing 🤩
wow very simple experiment but it demonstrates air pressure in a huge way! thanks so much for sharing!!!

Amazing.
👍👍helped alot🙂
Wow it's amazing
Love it bro
thanks for making amazing video
You're very welcome!
Best video ever seen
Sir...it is very helpful....explain us with real life examples...
hOw is the hot air is in the top while the temperature decreases in the above layers
pleeease i want to know
very cool
he explained me that i got 50/49 in my exam! Thnks bro!!!!!!!!
😊👍never give up
thank you
sir
Thank you for your explanation sir its very useful for my son we learn more about science sir

Hi,
Great demo, similar to one I like to do in my classes but with hot water. In your explanation about oxygen, you are forgetting that a combustion reaction also releases carbon dioxide, molecule for molecule, as oxygen is consumed. The CO2 exerts the same pressure as the O2 it replaces. The effect is purely due to air expansion.
Not to mention water vapor. You in fact have more moles of gases after than before. It's all about the expansion. You can see the water vapor that is initially invisible condense... like a cloud... especially when the bigger balloon enters the bottle.
exactly, for every 1mol of O2 u release 1,4~1,7 mol of CO2 and HOH, if u are burning something like a hidrocarbon, such as methane and propane, that does not have oxyygen IN its molecules (like ethanol, or a glicose polymer, like celulose - "paper"). If u burn glicose, is 1:2 (6 HOH and 6 CO2 for every 6 O2); The hot air that exits is then rich in CO2 and poor in O2, the air left in the bottle will be poor (or almost none) in O2, and rich in N2, CO2 and water vapor.
It is indeed about expansion; the heat air of the combustion increses the pressure till it pushes the ballon up, making it bounce, as it exits the bottle. Then, as the air inside the bottles "shrinks" because of condensation of water vapor and the deacrese in temperature, it creates a vaccum (since the ballon seals the bottle as it is being pulled in) and the ballon is sucked in.
wonderful
fantastic
Best science👌👌👌👌👌👌👌👍👍👍👍
My science class tried this, and it worked! One of my students wanted to record, so we did it again, and we almost burned down the building! You can see the video on his channel, startracker11, the video is called, "We almost burned down the whole yurt!" Great experiment!
Can u make a video is about air pressure and daily life??Like suction cup or drinking straw.Thank you so much!

Please can you do a video on air resistance? I need help on revising for my end of year exam.
Hey, check out the rest of our channel for more videos or email gmehler@temple.edu for requests. ruclips.net/user/funsciencedemosfeatured
my teacher has made us watch like every single air and air pressure video in one class
😂
My class thought this was SOOO cool that they want you to be our new Teacher nioce #YouDidIt
This is so funny😂
thanks
soooo cool
Sir ,why is the atmospheric pressure decreases with decrease in temperature at high altitudes?
But doesn't air pressure increase with heat? How does the fire in the bottle (which I imagine is increasing the air pressure) allow now the outside air (which now in theory is a lower pressure) to push it down? Unless the increased pressure in the bottle is escaping outside around the balloon and thus at that point leaves no or less air inside the bottle for atmosphere pressure to push the balloon in?
That's cuz fire needs oxygen to burn, and air has oxygen. When u burn something it means oxygen is depleting and it will lower the air pressure. That's the reason why outside the bottle's air pressure will push down the balloon inside.

Hi. What if in a inverted glass, dip into the liquid. And you want the liquid to go inside the glass ? Of course you will need a straw. But how can you suck the air inside? without the using your mouth to suck the air. What other devices you can use?
wow
You are related to my science teacher!:0 he told us
It would be awesome if this came with written instructions!
We're working on that! But in the mean time feel free to try it on your own! If you enjoyed this videos check us out and subscribe at ruclips.net/user/funsciencedemos for more videos just like this one!
when u press four he says air air over and over its so funny but dis video is good
love it

what is that thing called that has water in it
Thank you Jared!!! My niece and I loved learning more about air pressure. Noticed you weren't wearing a ring ;)
wtf
Wow
Can you plz make an easy future gadget?
nice
We saw this video in science class
That's great! Hope you enjoyed it :)
Would you please give me more experments ? Ineed it in my work..thank's a million.
+Mervat Shaheen Did you look at our full channel? We have hundreds of video demonstrations on FunScienceDemos! If there is anything in particular you would like to see, you can let us know and we will take your suggestion into account for future demonstrations!!

Why do u put the balloon in the cold water
Check out casy leer channel, he does a air pressure experiment.
U just woooowwwww
i use this activity in an event
thank you very much
Glad this helped, check out our channel for more videos and experiments! ruclips.net/channel/UCsbfPM5Wd1REwCIBYJFIyOw
my question is how does it relate to nature? plz answer me
ello jerry
Same I need HELP because I am failing science
Thanks for the experiment! I'm trying to demo it myself at home and am actually having problems with the balloon not going into the bottle all the way. I'm using a glass Starbucks coffee bottle, a regular balloon filled with water to the size of an egg and a piece of paper similar in size and thickness to a Post It note. I tried putting both the match and the paper into the bottle and that seems to let the balloon go in a little further, but I haven't yet got the balloon in all the way. Anyone happen to know what the problem is? My guess is that the paper needs to burn a little longer for more oxygen to be used up...? Thanks for the help!
Hello Katherine.....Seems like you are doing everything correctly. One suggestion. Before you light the paper, make sure the inside portion of the bottle mouth is wet. Sometimes the balloon gets stuck as it goes into the bottle. Good luck and thanks for using our channel FunScienceDemos.
Thanks for the advice. I've been wetting the bottle mouth and am having the same results...is it possible for the mouth of the bottle to be too large? A Starbucks bottle mouth is slightly wider than the bottle used in this video.

hello if your from my class
Hi mrs myers class its meeeeee if you see this comment
Oh, and don't forget that gas pressure requires a container or the gas will fill the available volume...

what's the learning can you tel me plzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz
LOL THIS STUFFS JUST PLAIN WEIRD.....BUT FUN
the ballon didt work to me
I am here for online school
