Mini hot air baloon

  1. Jan 15, 2012 #1
    First , i am sorry if i posted on a wrong section because im just new here .
    We , as a group of four ,need some ideas on constructing a hot air balloon with maximum diameter of 50cm (for balloon) and it should be powered only by candle (made or bought) with maximum of 3 wicks for our Physics Olympics (school competition). My problem is , i don't know what is the best material for the whole hot air balloon so it can lift up with weights on it ,and also how to construct a balloon (currently i am searching for guides on how to make) so i am here asking for some help . Thank you

    A quick calculation shows that you aren't going to do this with a spherical balloon think cylinder.
