How to make your own and improvised Hot Air Balloon?

I need the most simple one. No complicated materials. I saw some instructions on other sites and it says that I need a popcorn popper. We don’t use that in Philippines. Thanks!

I assume you are talking about a small model balloon and not something you can travel in.

I have seen ballons made of newspaper with a candle in them, however you would have to be pretty carefull as this is a fire hazard for you, the ballon, the take-off area, and the random landiong area.

You could also use drycleaning bags, they are very light, and perhaps a hair dryer,

Mass of hot air?

How do you find the mass of the hot air inside a hot air balloon needed for it to fly?
I have this info:
balloon volume
buoyant force on balloon
density of hot air in balloon
Can I figure it out with just this info and pretend that the temp. doesn’t matter?

It depends on the volume and the temperature. Since air follows the perfect gas law, air at 273 C has half the density of air at 0 C. The density of air at 0 C is 29/22.4 grams per liter. If you know the mass of the balloon and of the payload, you can determine the volume of hot air required at a specific temperature, or go the other way and determine the temperature required for a balloon of a specific volume.

What weather balloons to use to carry 200 lbs to 50k + feet?

What type of balloons should be used to carry a 200lb payload to 50,000 feet or higher?
Multiple balloons?
Precautions?
Calculations?

Every now and then someone will launch themselves into the sky using regular party balloons. There is an Australian movie about this, I think it is called “Danny Deckchair”.

The Cloudbuster giant is the finest rubber balloon for outdoor use available at any price. The unique formulation of chloroprene rubber includes UV inhibitors, which retard the sun’s ability to weaken the balloon. When filled to it’s rated size this balloon remains soft and pliable allowing for some expansion in hot weather. While more durable than a latex balloon they are not indestructible, so r…

what are good materials to make hot-air balloon fabric with and why?

I’d suggest teflon, the polymer used as coating for non-stick frying pans. its chemical name is polytetrafluoroethylene and it is non-flammable and it is stable over a wide temperature range . Considering the hot air in the balloon i’d say teflon is a suitable material.
