Can anyone point me at a decent portraiture DSLR camera for under $700?

Can anyone suggest to me an iOS app for creating pixel art? Preferably ones that have cloud storage.

This or this?

Why do sparkling beverage suddenly loose all their dissolved CO2 when you shake them?

[LordSlowpoke]

it's not dissolved co2, it's carbonic acid

carbonic acid is volatile, shaking it breaks it up into carbon dioxide and water

carbon dioxide fucks off upward and water stays where it is

I'm looking for what'd basically be a plastic tubing, only a web of it instead of a single straight tube. Google is useless because all the search terms I can think of turn up tubes, made of mesh or weaves or whatever. Any tips on what I'd actually be looking for, here? Looking to have a way of circulating fluid over a flexible surface, and it'd simplify things a lot if I don't have to weave a tube on itself or try to manually add branching and stuff.

carbonic acid is volatile, shaking it breaks it up into carbon dioxide and water

carbon dioxide fucks off upward and water stays where it is

Which is produced by dissolving carbon dioxide in the water. Under high pressure, thereby forcing the reaction equilibrium (H2CO3 <=> H20+CO2) towards the formation of carbonic acid as per Le Chatelier's principle.

My bedsheet is starting to go mouldy, so I guess I should wash it. Is it okay to just chuck it in with a load of other washing?

Also, Bauglir, I would have no idea.

[Aklyon]

Should be fine I think if its closeish in color? assuming you don't try to wash too many big blankets and sheets at the same time anyway.

[LordSlowpoke]

while you hardly have to worry about the colors mixing nowadays, it's still wise to wash it with things that are closeish in colors or at least make the distinctions between dark and light cloths

i think the thing is that you wash bedsheets at a higher temperature than you do regular stuff?

and yeah overloading the washing machine is a terrible idea too

[Reelya]

Hot water is needed to kill dust mites in sheets. 130+ degrees Fahrenheit is required for that. Also, eucalyptus oil is highly toxic to the little fuckers, some people recommend putting some in with your detergent.

how do I use spreadsheets

[MagmaMcFry]

Every field has a content and a value. By typing in the field, you set its content, and its value is calculated from the content. Usually the value is exactly the same as the content, but if the content starts with an = sign, it's treated as a formula to calculate the value. For example if you enter "=2+4" into a cell, then its content is "=2+4", but its value is 6. Note that the spreadsheet program usually displays the value of the cells, unless you're editing it, in which case the content is displayed. Another example: If you enter "3" into Cell A1 and "=2+A1" into Cell A2, then A2 will have the value 5. And here's the best thing about spreadsheets: If you edit A1 to "7", then A2's value will automatically update to 9. This is the power of spreadsheets. Use it wisely.

Okay, geometry question.  Note that I am not a math person, so this may be worded awkwardly.

Using Schläfli symbols:
{3,3} = Tetrahedron (or a d4)
{3,4} = Octahedron (or a d8)
{3,5} = Icosahedron (or a d20)

So what the hell is a {3,6} if such a creature exists?  How many sides does it have?

3 Hexagons around each vertice... yea, I don't think that fits together to make anything neatly in 3d. Possibly some kind of triangular grid, if a quick sketch is anything to go by?

Actually, I think it's supposed to be 6 triangles around each vertices.

whats the name of that show its like have you been paying attention but on the abc and each episode they have a guest star make a cocktail
