- Two balloons are inflated by about the same amount. One balloon contains only air. The other balloon contains a little bit of water in addition to the air. Each balloon is placed above a lit candle. Which balloon pops first?

Cant believe it has been 15 years 😢
Love your content! Thanks 4 explaining concepts
Played with a much smaller amount of water? Wondering if the results could flip if the water in the balloon reached boiling point quickly(steam expansion being what it is).
I assume that, if there's so little water in the balloon that it can be brought to a boil quickly, then there isn't enough water to effectively protect the balloon.
@@JeffersonLab Plus if the temperature the candle provides to the balloon reaches 100C, it's likely the rubber would weaken regardless, mitigating any difference. It would be interesting to know what the temperature at the bottom of each balloon was upon popping.
What happen to this series? Where'd it go? It's been a while.
The "Here's a Question!" series was always planned to contain 42 episodes. This particular video was the 42nd.
Its existence is a fluke of the pandemic. There was a period of time where we (employees) had returned to the site but our on-site student programs had not. So, the room in which the videos are shot was available throughout the summer of 2022. Because of this, we were able to record all 42 episodes over a 10 week span without needing to continuously reset the room. From here on out, we return to our 'whenever time permits' recording schedule.
@@JeffersonLab Thanks for the update. I really enjoyed them.
@@JeffersonLab so what is the next series of videos going to be about?
@dirtymike4894 Yeah, they were fun to do. Really filled up that summer, though.
@daily623 It's not exactly a 'next series'. We're just returning to our more standard Frostbite Theater style of videos. Probably a couple will involve liquid nitrogen. Maybe measure the speed of sound. We're still mulling things over. Still have a few weeks before the room is once again free for a semi-extended period.
Watching your 10 year old videos ...your brilliant sense of humour...😂 Is awesome ..love your content ...keep uploading and interacting with audience like usss
We'll do our best!
I thought this might be a trick question. But I went with common sense
I have confused my nephew and niece with this 'trick'. I don't have to guess what happens. :D
I think b
Because water help the balloon resisting the heat for a bit and the O2 is less at water balloon
Cool beans
i dont know where to ask this as i dont use twitter and i hardly use insta so ill just post it here and hope i get a answer. i really want to know is it possible to get to space with out liquid chemical rockets? cos in the far off future or probably not with our exacerbating usage of it. all fossil fuels in the world will have been used and we wont have any left to propel us into space. is it possible to use renewable resources to get us into space?
Without liquid fueled rockets, specifically? Yes. You can use solid fueled rockets. There's also the possibility of a 'space elevator', where material could effectively be 'lifted' into orbit. Things become easier if you choose a different startling location, like the moon. Since the moon doesn't have an atmosphere, you could 'fling' material off its surface using something like a rail gun.
Lots of rockets don't use fossil fuels at all. The space shuttle, for example, used liquid hydrogen and liquid oxygen for its main engines and solid fuel for its boosters. Nitric acid can be used with hydrazine (although neither one of those materials is especially nice on its own). The Soyuz spacecraft uses hydrogen peroxide as a monopropellant in its descent engine. The modern push seems to be methane and liquid oxygen. This is to be used in SpaceX's Starship, ULA's Vulcan and Blue Origin's New Glenn, had has already flown with LandSpace's Zhuque-2, Firefly's Alpha and Relativity Space's Terran 1.
Now, is methane renewable? Sure, if you make it from renewable sources. You can make 'fossil fuels'. It isn't as if it's some unknown chemistry or magical material. Synthetic oil is a thing. It's just that fossil fuels are convenient in terms of energy use because the energy needed to make them has has largely been paid. You can make methane (and water) from hydrogen and carbon dioxide through the Sabatier reaction. It takes energy, though. If that energy is coming from some sort of renewable source, then you could consider the methane that's produced to be renewable.
Almost too easy. Ever try to solder a pipe with water in it?
Sir i am from india class 9th i want to talk something to you about physics. Please try to reply ❤❤❤ Love your videos
Make short videos please
You don't consider two minutes and twenty-one seconds to be short?
@@JeffersonLab Many people are becoming famous by creating short videos using your hard work. Kindly consider creating short videos. Thanks a lot for your excellent videos.
