Physics of toys- Cartesian diver ideas-part 1

Part one. Cartesian Divers are a fun and simple experiment that is easy to do for any age. The basic experiment starts with using a soda bottle and divers made out of droppers, straws or other materials. This video take a look of suggestions to make the demonstration a bit more interesting. Spinning divers, remote control divers, how many divers can fit into a bottle at once. Continue on to part two takes a look at making larger divers.

2:50 The spinning version looks cool. also the remote control is a very nice addition.
I once saw a game made of this experiment where there is a small hook attached to the diver and there is a small treasure sank at the bottom which you need to use the diver to pick it up to the surface.

Thanks Bruce!

This is easily one of my top five Youtube channels.

Science is amazing Bruce. And you make it fun and interesting. Thank you!

Awesome Bruce! You make my day with your videos

You also can have interesting result having a bottle with not round, but elliptic section. Having 1 object barely floating and 1 barely sank, you can make both floating or sinking together by squeezing bottle in different directions.

I was very impressed by the various versions of the Cartesian diver experiment that you presented.
Currently, I am constructing a 1.5-foot glass cylinder and am facing challenges with sealing the cylinder to ensure the diver functions properly. I would greatly appreciate any guidance you could provide on how you sealed your larger cylinder in your last Cartesian diver idea from this video and what materials you used to prevent air from escaping, which would allow the diver to dive effectively.

I liked the royality free pirates of the caribean tune. Science on the open seas!

Soda straws are easy to find. Those plastic toys may take a trip or three to various dollar stores to find. But well worth it to spend time with the grand kids. What happens if you reverse the idea and place a diver that sinks and introduce low pressure into the container? Thanks for sharing.

[JoaoZagoSJC]

Can we have "serial divers"?

I mean a huge bottle with a medium bottle inside of it with a diver inside the medium bootle?

Would both sink?

There is no bye maybe see you later and great video !

Came for the Garfield, stayed for the science!

Whoever is edditing all of this unreleased content, thank you! I didn't want to accept his passing but this helps. Thank you Mr Yeany. I hope you're looking down at all of us
