Warm Air Rises_Making a Birthday Candle Hot Air Balloon

Jared makes a hot air balloon with a plastic bag and birthday candles! Click on this link: learningscience.... It will take you to learningscience.org, where you can find lots links to fun, interactive science websites designed for kids.

It is a dry cleaner bag🙂 For those of you wondering🙂

[@alexhardin6968]

if it isn't lifting up, try cutting the candles in half, it lessens the weight for an easier take off

[@Tatusiek_1]

Alex Hardin Or use 3 straws, if you cut the candle, there will be less fuel

[@Sniperdead-df7mq]

Cool! this really helps me and my friends cause where building a hot air balloon so uh...... Thanks!

THANK YOU FOR SHARING THIS FANTASTIC EXPERIMENT

[@YoutubeCommenter1]

Your safety glasses are AWESOME!!! WHERE DID YOU BUY THEM??????????

[@yyuliang]

It looks SO COOL!

[@sciencetoymaker]

You did a good job of showing the assembly. However, typical retail household trash bags are made from plastic that is too thick and heavy for making a hot air balloon. Fortunately, the the thin, light-duty bags often used in offices and schools are perfect.

"I dont want to lift it" *lifts it*

[@GeloGoes]

Can a lightbulb heat the air around it enough to make air rise like this?

[@HolyCrepe]

noe, a lightbulb is wayyy too heavy

[@Tatusiek_1]

Kaaro He said the air, not the bulb. Please read properly

[@cindyrobertson3798]

Cool I want to let some fly at new years! Snow, no fire danger

[@trevabenjameen2858]

THANKS FOR DOING THAT :)) .. IT IS VERY HELPFUL

[@arcdude2000]

What kind of bag did you use? It looks like a trash bag?

[@SarrouTube]

Very good demo

[@danbogaczyk1631]

I use to make these in the 60s but used dry cleaning bag and put slits with razor blades and stick Birthday candles in them around six a cross on each straw the bag would get way up in sky and start moving people where calling police and stated a ufo was in over the city ,when it got up in the night sky looked big as a house

[@DinaAbdelsalam-b6b]

Is there a link to buy the bags from?

[@pamelaharris5055]

Thank you for sharing this idea. Now, time for me to practice. :-)

[@ratdad48]

I just watched a guy wearing safety glasses because he was using scissors.

[@aryankhemka1412]

in my one the plastic burns

[@novavlog3642]

Nice flying

[@vedickalra9796]

you should have tried the hot.... outside

[@sxnny_dae4258]

Ah yes *tried the hot*

[@danielnoorlag9252]

Is it possible to provide a link or say where you got this bag?

[@jaroach55]

How do you do it without burning the plastic

[@WeatherDemos]

+John Roach You do have to be careful, but there should be enough space between the candle and the bag itself. Watch the video a few times to understand the technique. Also, we use bags that are .25 mil and under so that they are light enough to be lifted.

[@princessguaina5713]

Can we use ordinary candles?

[@rajesh.dyadav9089]

Thank you for making hot air balloon

[@ilmerazasyed4171]

i like it but i did not understand

[@aryankhemka1412]

nice man

[@Its_CR713]

👌👌👌👌

[@hoodboy4104]

Did you really need safety glasses lol

[@chloeloo7982]

hmmm....
I wonder if you are a Science teacher! -w-

[@HelloFutureUSteachers]

It helps. Science rocks!

[@otterscorner1670]

Cool goggles ;)

[@mikecochran1759]

Its crazy but i am going to half to call BS on this one. I have tried this like ever which way including making my own bag out of just thin plastic i had and in every test the candles melt the bag.
I can not get this to work. You for sure can not do this with one of those bags you get from the grocery store. believe me i have tried. The melting point of the bag is before the lift of the hot air made by the candles. 2 candles cut low will fill the bag with hot air but will not lift it no matter how light you make the armature holding the candles. I had 4 candles as thin as i can find cut to just a 1/2 inch stuck into the straws themselves, i didn't even use the foil and all that. Lit 2 of the 4 candles and nothing. as soon as i lit the third candle the bag melts. What bag is this guy using ?????
flame and heat retardent????

[@isabellatowns255]

Helpful thx
