How to Make a Hot Air Balloon Part 6 Using Small Bags

[eejay30]

if any of these hot air balloons work, how much cubes are inside 1 to 2?

to get here i looked up "How To Make Air"

This was so helpful for my IB experiment! :)

I would so take firecrackers and put them on this and fly it into my neighbors chimney! }:D MUAHAHA!!

The best bags are dry cleaner bags, balso wood. birthday candles, cleaner bags have a hole in the top for ventalation . Balso wood is flat, good for adding the candles. should take 9 b-day candles for good lift off.

cool. i got an idea. ok now that the cheap one has volume as the limitation. u can "hack" it. get 2 or 3 and cut the ends. then connect the bags one is not a hollow cylinder to make a long balloon though its still not have big diameter double height so almost double volume. but may need to hold up longer so that it dont collapse until the air can lift it above the flame

how come it burns the end of it how many candles should i put

[sciencetoymaker]

@gabrielgonzales0902 The top melted because the flame was so close. As I said, using these small produce bags is experimental. The larger (but still very thin plastic) trash bags always work. But you'll have to experiment with these small ones. It will help a lot if you do it on a very cold day. The cold air will both increase lift and might keep the plastic cool enough that it doesn't melt.

well,can i use a small plastic bag?is like the sandwich plastic bag

[sciencetoymaker]

@JuliaElise383 No, but if you want to go very simple and easy, do a search for TEABAG HOT AIR BALLOON

Fire Hazard !! for wooded areas. This one looks a little safer cause of the small candle. not like others you see on Youtube.

nice

keep it up

[kenth65]

SO the bigger hot air ballon the better i fly's

[sciencetoymaker]

Yes, bigger is more efficient because the ration of volume to surface area becomes more favorable.
