how much helium to i need to lift something

[littlepigboy5]

I need to use baloons to carry some small stuff up to a window, not heavy stuff, flowers n choclates n shit.  how do i know how much helium(inside a baloon though, so i have to add the weight of each baloon) i need to make something that weighs a certain amount float?

This has to be hands-down the best question I have heard so far today .... I dont have the answer, I wish I could help .... but I love teh question. I would go for trial and error ...

 

Am I right in guessing you are trying to impress a lucky girl, I love your romatic description  (flowers n chocolate n shit) of how you are going to make her girlish herat do cartwheels ...

 

Good luck

A lot. 

100 balloons will not lift a violin, that what I found out.

I could see it going wrong, just floating past the window and into the sky forever lost

it depends on the object you're trying to lift...

 

heavy object = more helium needed

That STRICTLY depends on the weight of the payload.

 

You need to know the exact weight, it would be best to have it measured to a single gram, or even more precise.

 

From what I understand, you want it to lift slowly to the window, not to go slowly to stratosphere... Therefore we need the exact payload in order to calculate the exact amount of helium that would lift said payload at, let's say, 5 centimeters/second. It's not that hard - but it's more complicated than it sounds. 

 

Also, you're going to need a way to fill your baloon with exact amount of helium if you want it to succeed. Not enough helium - it won't fly. Too much helium - it'll fly right past the window and into LEO.

and she doesnt make the effort to notice it or try and grab it ... the gesture will be lost forever and he will NEVER be believed !!!

i haven't bought the flowers or choclates yet so idk how much it weighs, but still really helpful.
