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 ?
