    Hi, First of all i want to say sorry if my language is not good enough to explain because English is not my mother language
    And sorry if I post this in a wrong sub-forum

    So I have an assignment from my college about Physics, specifically Fluids
    In a team of about 7-8 people We have to make a mini air balloon based on Archimedes principle..
    And the minimum requirements are :
    1.) Able to fly 0,5 meter above its initial position
    2.) Fly about 1 minute
    3.) Max Mass of the source of heat : 20 gram

    The questions are :

    1.) What material that if burnt or act as a heat source could produce great energy in a minimum mass ?
    So the thing that is commonly used is candle, maybe tiny ones, but I think there are things greater than that..

    And I hope the material or the thing is easy to find or build..

    2.) The shape of the balloon could be anything; Sphere, Cylinder, Cube, etc.
    What do you guys think the best shape that could make it efficient and effective to fly ? and why ? (that rhymes ! )

    Also what do you think the material of the balloon should be ?
    Plastic, Rubber, etc ?

    one thing you could have a look at online are things called garbage bag balloons. i guess go from there.

    hope this isn't against the not doing homeworks rules.

    Sometimes it is better not knowing than having an answer that may be wrong.

    As for a heat source a magnesioum strip would be spectacular but a railroad flare would also be neat. A five minute one might be light enough.
