What would cause a fresh, tree-ripened lemon to lose it's flavor?

A friend recently gifted me with a dozen beautiful lemons, picked right from his trees.  I juiced a couple and got nearly 1/2 cup from each lemon but the juice tastes almost nothing like lemons.  The flavor is remotely citrus but not at all what a lemon is supposed to taste like. What would cause this? Does anyone know?

When life gives you lemon pips...

A friend just brought us back a lemon she picked (with permission) from a grove in a convent garden in Rome. It was very tasty, and had five pips in it.What is the best way to grow these pips on into a new bush or tree?I don't have a greenhouse, but I do have windowsills. I eventually plan for the bush / tree to end up in a large pot.(I know I could google it, but do you happen to know whether lemon trees have gender? In other words, would I need two trees to get fruit?)

How can I dehydrate lime or lemon juice to make a powder?

I'm interested in using dried lime juice powder in place of citric acid powder for things like dusting fruit leather to make sour fruit candy.  Can't you just leave some juice out in a shallow pan in the sun and then powder the result in the blender?

What kind of electrodes can I use in a lemon battery?

Dear Instructables community, recently I stumbled upon this instructable: https://www.instructables.com/id/The_micro_Lemon_Battery_reusable_1_hour_of_led_l/ and I immediatly recognised it as a nice way to spend an afternoon. Now here comes the question: Are there any alternatives for zinc? For instance this instructable: https://www.instructables.com/id/Salt-powered-LED-flower/ uses copper and aluminum foil, instead of copper and zinc. If the previous question is answered with no, then could someone please tell me where I can find zinc? I mean something like: break open this device, there will be some zink in there. If you feel like it then feel free to explain the principles behind electrochemistry to me. Always happy to learn something new. Thanks in advance, Dennis van Rooijen

What can I do with all this lemon balm?

Last summer, I rescued some plants from a friend's window box that were looking dangerously wilty.  The basil and parsley died, but the lemon balm took root like a weed and now covers a two foot square patch of my garden to about knee height.  It's going to have to be cut back before it takes over the rest of the garden like tiberium, so does anyone have suggestions for what I can do with a bushel of citrus-y herb?  I hear the essential oil is used in aromatherapy and has antibacterial and insect repellent properties- should I make like Kiteman and distil some oil?

I have glucose tabs (for diabetics), which I think are much more pure than sugar, would this help my plants grow better?

I am trying to grow citrus seedlings and have been finding mixed reports about the affects of sugar water (instead of just using regular water). I was wondering if glucose tabs, being more pure than sugar, would help my citrus plants grow.

How do you concentrate citric acid? Answered

I'm making this thing, and I was wondering if concentrating the citric acid (from calamansi (Philippine lemon)) would increase output. My friend suggested boiling it, but is there any other easy way of concentrating it? If not, then let boil.... For the meantime I'll boil it to check if it works. If results come back positive, I'll delete this question. If results come back negative, I'll let this question float around instructables for a while. (Please do help me in putting this in the right category)

If I put lemon juice in one cup, ammonia in another would I have made a battery?

I couldn't fit all of this in the question box so PLEASE READ BEFORE COMMENTING. I read that acids put in water release H+ Ions and bases put in water release OH- Ions. If I put water proportionate to the amount of what I have in the cup, and added wires to connect to a circuit, would I have made a battery? P.S. The picture was made in MS Powerpoint for anyone who wanted to know.

floppy disk/ iron oxide sheet use?

I saw the ipod charger using lemons here: http://www.thenakedscientists.com/HTML/content/kitchenscience/exp/charging-ipods-with-lemons/ And I began to wonder what would happen if  you sandwiched a bunch of floppy disks together and put them in a solution... Hook them up in series and well what? Could each one be used as a tiny cel in a battery?  I am going to look around, I'm sure my colleagues are still hoarding floppies. I think I'm gonna need a lot of alligator clips on this one...Must be something a sufficient number of floppies can still do for us.

Periodic table of condiments

Nope, that isn't a typo. You've heard of the periodic table of elements? Well, check out this hilarious table of condiments that periodically go bad. From Condiment No. 1 (Mayonnaise, which the table says goes bad in 3 months) to Condiment No. 75 (Maraschino, which apparently never goes bad), you can look up just about any condiment you can name to see when you need to toss it out. Or at least when these people think it goes bad.Take it with a grain of salt (Condiment No. 2, it never goes bad!) though-it claims Lemon goes bad in 2 months. Stuff and nonsense. I've eaten 3 month old lemons that were perfectly good.Mendeleev would be so proud...

2 New home-made chocolate ideas I have (sort of) come up with!

I have just been inspired by the Peanut Butter Cup recipes, to make some for my family.. but I decided, that since some people have nut allergies, I would make some filled with Lemon Curd... a little odd, but it works... they are cooling at the moment.. but I had a sneaky taste of one! but I ran out of Lemon Curd (only had 3 teaspoons of it!) so I rumaged in the freezer, and found some frozen raspberries from last years harvest! basically I crushed 3 into each muffin paper, and covered in molten chocolate... I think these are even nicer... (instructable being written.. will have to photograph batch 2!!) Has anybody got any other interesting chocolate recipes?? I was thinking maybe some crackling sherbet to go on top.... Will (AKA IllegalFun)

I have Googled and searched Wiki on how to make fluorescent (ultraviolet) inks. I want to know how to make them. I dont want th lemon juice , corn starch, milk or other types of invisible inks. I want to make the stuff the glows under uv light. I searched using uv, ultraviolet, fluorescent inks but couldnt find anything other than the lemon juice and other types of "invisible" writing. Please help if you know where to find or if you know how to make fluorescent (ultraviolet) inks. You can email me at whitethatchpotentloins@yahoo.com I mean the inks that u can buy for handstampers and that are put in invisible ink markers.
