is it possible to turn a full 30cm cube volume of glass jar upside down without spiling the contents?

Put a rubber stopper or a lid on the glass jar.  You can turn the jar anyway you like, nothing will fall out.

I don't think you can convert that.\n\ngrams measure weight\ncups measurse volume

volume = length x width x height

The first problem is that a true Klein bottle cannot be made in three dimensions. The ones you can buy are 'Klein bottles with a hole'. \n\nTo make a Klein bottle, let's first make a torus (a bagel shape). Start with a circular cylinder, and label the two circles on top and on bottom with little arrows pointing the same direction around the cylinder. Then glue those circles together so that the arrows go together. This is a torus.\n\nNow do the same thing, only have the circles go in opposite directions around the cylinder. You will find that to glue the circles together, you would have to push through the side of the cylinder and glue from underneath. If you imagine cutting a little hole so this can be done, you have a Klein bottle with a hole! Now imagine filling in the hole, but *not* causing any intersections. Again, this can't be done in three dimensions, but it can in four. THe result is a true Klein bottle.\n\nThere is a misunderstanding that non-orientable surfaces are always one-sided. This depends strongly on what space they are imbedded in! When in Euclidean space, this is correct, but if they are imbedded in another non-orientable space, they can be two-sided there. Non-orientability has to do with whether there is a way to get a consistent 'circulation pattern' over the whole surface.

Turn it upside down to get all the liquid out and let it dry.  Then use alcohol on a cloth to remove the sticky stuff.

The simplest way to do this would be to use the Paint program that comes with Windows.\n\nYou can draw simple geometric shapes.  Then you can select one, paste a copy, then rotate/reflect the copied shape with Image->Flip/Rotate menu selection.\n\nThat ought to do it.

just multiply the side of the cube 3 times

Here's a tutorial to do just that. Follow the link!

Try a company called Eurocold

Only on the concave(front) curve of the spoon will give an upside down reflection.  The distorted surface of the spoon reflects light from yourself at angles which result in an inverse image in the spoon.  This is actually called refraction.

shape it into a brick divide its mass by its volume

jus click on it and hold it down..\nand drag it to where you want.

Select the object or image and then press the modify menu, transform, flip horizontal.\n\nso in the menu bar - Modify > Transform > Flip Horizontal.\n\nWould have been much easier if it said mirror :P I just figured that one out for you. I might muck around with it now. Hope this helps.

Use a flat knife with no ridges, and be careful!\nSlide it through the coin slot and flip your bank upside down.\nI have a beautiful glass piggy that was my sons at birth and didnt want to break it, I managed to get out a good majority of the coins this way!\nGood Luck! :)

there are a number of commercially available programs that can perform that type of conversion.  One that I've tried that works pretty well is Solid Converter PDF.
