Sink or Float Soda Cans with Relative Density

Salt can be used to increase the mass of a solution without drastically changing the volume, making it easier to float objects in salt water! Demo presented by Geoffrey Franceschi.

Nice little demonstration, keep up the good work!

[@tamuphysastr]

Thank you. Will do!

I am going to use this one in my classroom ! Thanks for the demonstration ! 😄

If you keep the salt water you can use it for a follow up on crystals if you put strings in the water to form crystals around the string. You can also colour the water too for coloured crystals. This way you get lots of experiments an no waste.

Nice work

Plus the sharks like their salty snacks just like people do.

Cool demonstration!
Don't swimming pools have chlorine and such that would also increase density?

[@tamuphysastr]

Chlorine does indeed have density but I believe you would need a very large amount of chlorine in the water to see the same effect as salt in this video.

Which is why it is easiest to swim in the ocean, then a pool, and hardest in a fresh water lake. And in pure H2O you sink like a rock.

Why does salt increase the density of water?

now i see why it's called diet soda.
