How large of a soda can would I have to use in order for the can to be able to suspend itself if filled with helium?For example, a regular 12 oz aluminum soda can weighs 15 grams emptyCan filling it with helium provide enough lift to suspend it? The volume of a 12 oz soda can is about 25.6 cubic inchesWould either a standard size 12 oz aluminum soda can (15 grams weight empty) or a standard size 24 oz aluminum soda can (25 gram weight empty) work? If not, how big would the can have to be to suspend itself if filled with helium?Would less helium or more helium be required to suspend it if the can is put in a freezer until it reaches 0 degrees fahrenheit and then is brought to room temperature?I believe that we will need to calculate buoyancy to figure this out, but I'm a bit lost as where to startThanks for your help!!
