Kids, don't try this at home: it's almost certainly not a good idea. But for those of you who are interested in physics, note several important points:

(1) The rocket fires under water: that works because it's a true rocket, carrying both fuel and oxidizer on board and not using air at all. The shape of the nozzle is also important, since water has an amazing ability to absorb heat and thus quench combustion; a caul around the nozzle keeps the water from getting at the ignition point from the sides.

(2) The primary explosion creates a roughly circular set of cracks. Those lead to "big" cracks opening up in the ice, as existing seams and weaknesses get expanded. 

(3) Note that the circular cracks become hexagonal (matching the big cracks) as you move outwards. What's happening is that the inner cracks happen first, and then those start the big cracks, which actually spread faster than the round ones, basically moving at the speed of sound in ice. By the time the last round cracks are forming, they're forming in ice that already has hexagonal cracks in it.

(4) Water is an incompressible fluid, which means that the shock waves are going to hit things under water very, very hard. This is likely to be lethal to anything underwater and nearby, and is how dynamite fishing works. The reasons why that's a terrible idea (and is therefore illegal nearly everywhere) are hopefully obvious.

(5) That said, watching things explode underwater is pretty cool.

So the new Google+ Layout Looks Like Facebook? Really?

Yesterday Google+ rolled out 41 new updates to the platform. Among these updates was a somewhat radical shift from what most users were used to. I personally am enjoying the new look, especially since it gives lots of love to photos (including vertical images that were previously cropped in our streams). However with any change there are certain to be people that are left unhappy. 

One of the most common comparisons is that the new Google+ looks like Facebook. Being a photographer and a visual artist, I decided to draft up a simple comparison to show you that they do not in fact look alike.While my monitors have a large enough resolution to showcase three columns, even the two column version has a much different feel and vibe.

So like it, love it or hate it, atleast make accurate comparisons if you are going to try to prove a point...even if that point is that you are just unhappy with the new look :)

Matt, I know you probably won't see that here but you should join Google+ with these great circles you are creating ;)

+Debashish Samaddar and +Alok Tiwari thanks a lot for pointing us to Matt and showing us that the post we have previously reshared was just a copy of the original blog post without giving any credit.
It's a shame to see such behavior here on Google+. Sorry for supporting that by a reshare (which is deleted now).

Thanks also to +Alex Ander for the reference to "Circular Gallifreyan" and to +Gideon Rosenblatt for the reference to "a lo-rez Mandelbrot Set" in the first post we had. Sorry guys for deleting also your comments by deleting the post.
