My sister needs to make a model hot air balloon.

[Smith]

Its for her science project. Does anyone know a site where I can find plans on how to make one?

I swear I remember my teacher making one out of paper and a tea candle when I was in elementary school. Anyone know?

tea candle and a plastic bag :dabs:

[GepperRankins]

i wanna make one know :lookaroun

[tesco]

take a plastic bag, tie it up to a candle holder, light candle and put in candle holder, hold up bag until it inflates.
Not a hard concept.

Maybe you can find something in
www.howstuffworks.com ???

Full a balloon with lighter gas,
cover balloon with paper mache, allow to dry.
paint it with ya favorite hot air balloon colours ~ let dry

cut a small hole at the botton, pop the balloon inside, and ignite the gas

should work ok


edit: due to bad spegling

I'd agree, except for the lighter gas thing (WELL DANGEROUS!!) :frusty:

Papier mache is the way to go.

Just blow up a balloon, cover in papier mache from tissue paper, then pop the balloon, and cut a hole in the bottom.

Use some thin wire to fashion a cradle in which you can support a tea-light at the bottom, under the hole.

Attach the two, light the candle, and hey presto, a hot air balloon. If it's light enough, the heat from the tea-light should be enough for it to fly...? :ermm:

My sister

FYI, I don't think he's trying to replicate the Hindeburg incident.

It might look really cool, tho'.

:lol:

Yesterday I took a bag and opened it and put it over stove (gas) and it inflated a bit but got hot and started to melt so i stopped.:unsure:

I think the heat from the tea light will set the paper on fire, but my sisters trying that anyway.
