Draw an iceberg and see how it will float! We often draw icebergs vertically, with a little tip above the water, and a giant part under the water. This doesn’t work, it wouldn’t float, because of mass distribution. If you want to have fun, draw your best iceberg, and see how it would actually float!

@stephaniewalter This looks like it would be a fun science class activity.
@dan613 I teach earth and environmental science classes sometimes (US middle/high school), and I am definitely going to use this when I teach it next! Thanks @stephaniewalter for sharing this!

@stephaniewalter i used it countless times in meetings. most of the versions used in slides are falling over ;)

cc @josh

maybe its time for a podcast episode about physics vs. psychology of iceberg models?
@NadjaBoehlmann @Alisa @mariakuehn @karen

@stephaniewalter if you are so inspired, pop by #Newfoundland in the spring and see them in person ;)
@cowman @stephaniewalter I can't even imagine how large this one must be under the ice. How deep is that channel?? This was likely taken with a telephoto lens causing scale compression, but still...
@dan613 @cowman wow, that's a very nice one indeed. Must be giant under the surface
@dan613 @stephaniewalter Tough to say, though it is probably grounded so the immersed buoyant volume isn't at play.
@stephaniewalter There's something wrong with the simulation. Draw triangle in top-left corner. Watch the crazyness. Draw same triangle in the middle, and it behaves differently.

@stephaniewalter this is the most zen thing I've seen in a long time.
@stephaniewalter It's the climate change's fault.
@krystman damn, I'm here for the chaos and laughed hard at tis one. thank you
@stephaniewalter it does depend on the objects starting position, though. Very interesting.

@stephaniewalter
Did I start by drawing inappropriate shapes?

I will neither confirm nor deny.

@stephaniewalter welp. I know what I'm doing during Teams meetings now
@stephaniewalter I love this! Thanks for sharing.
@stephaniewalter oh I'm gonna have way too much fun with this

@stephaniewalter

Thank you, I had a lot of fun with this back in the day and I didn't remember it!

@stephaniewalter if you make a short 2D stick in the air and let it drop into the water it will flutter around and spin endlessly.

@MikePfeifer @stephaniewalter

Yeah I was going for dynamic motions.

This one rotates a bit.

@stephaniewalter safari won’t open it. Says it isn’t a valid address.
@stephaniewalter chrome won’t either
@DanadasGrau oh, snap, indeed it's down today, that toot got a lot of success I hope it didn't ddos
@stephaniewalter me, designing an iceberg that rotates as it settles so that a pointy bit stabs upwards into the sun: hell yeah little buddy, attack and dethrone god
@stephaniewalter Oops! I made an iceberg that is infinitely unstable (not really - just in the simulation)
@cathos hhaa the level of chaos, you found a glitch in the system
@stephaniewalter Can we please have little penguins added that appear when the iceberg has leveled out? 🐧
@stephaniewalter
I made a cool one. Thanks for the cool tool :-)
@stephaniewalter there's a pattern forming here.
@Niall and here goes your Sunday afternoon
@stephaniewalter I'm in NZ so it's past bedtime on Sunday here. There goes my early night!
