  1. 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 ?

     

    Thanks
