    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?

    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.

    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

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

    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...?
