How long would these stay hydrated? And would you need to keep water in them to keep them hydrated? Would they begin to decompose or fall apart?

They will stay hydrated as long as they have water, for up to about a year. Changing the water to avoid contaminants from clouding the water is necessary. If they are exposed to the hot sun for an extended time they will turn to mush.

We kept ours for play for at least 2-3 months in a plastic storage bin. They did not fall apart and stayed hydrated. They might have shrunk down a little but it was very slow.

You soak them for a few hours or so, then after that you can drain them and leave them in a bucket. No, you do not need to keep them in water but after about 3 weeks they start to smell. They don't decompose however when kids play with them or step on them they fall apart. It is kind of like a more durable form of jello.

Water tight, very much so. Air tight? Well, sort of. I wouldn't store a gas in them, if that is what you're asking. You don't smell anything if you've got something gross in there (that's happened a few times). But they are probably only about as air tight as a plastic bottle. So, some air is going to escape, it will just be slow. So I guess it depends on what you're planning to use them for.

I can't imagine why they wouldn't. However, you can't soak them or they dissolve into dust so that could be a problem

I wouldn't submerge these in water permanently. A strong rain or being temporary submerged isn't a problem as long as it's not cracked from what I've seen.

They come dry, once you get them and when you are ready to use them place them in warm water in order to make them expand. They will stay expanded for a couple of weeks once you see them shrinking place them in warm water again so you can re-used them

These can be refilled with water. Distilled would be best. You can also use Xikar or Cigar Caddy use everytime solutions.

I suppose you could but staying watertight over the longterm may be a problem. They seem to be sealled pretty well but I would defer to the manufacturers opinion for this use. They would look cool while they lasted anyway...

No!! They are fully dried and do not need refrigeration, at any time while they are in the dry state. Once you add water and re-hydrating them yes they need to be refrigeration.

yes and no. they don't absorb moisture right away. so the sweat off your drink will pool and roll off. Then if you leave it sit long enough it will swell and get trashed (it does take a long time).

They are freeze dried so should last indefinitely if sealed. If left open, moisture could get in and cause spoilage.

You can keep them in a plastic tub either at room temp or in the fridge. They will pupate after a few weeks at room temp though. I keep mine in oatmeal and with something for water like a carrot or potato slices.

Yes. When you hydrate them, they swell up a lot. It should be far more than you need.

No, you throw them in the freezer for a few hours and they last longer then ice cubes, and obviously don't water the drink down.

Only if you fill them with a dry ingredient. No liquids or they WILL dissolve.

I really dont kno because I didnt actually put mine in water, I wiped it down real good. Only because, I didnt buy them to use I bought them for decoration and not to be touched...im sorry I couldnt help.

Truthfully, not as long as I wished. If you eat them while drinking a lot of water I stay full for longer. Probably an hour or two.

Like others have said, these come in a heavy ziplock bag. Mine lasted through about 3 seasons and I stored the unused ones in a cool, dark place. I live in Alaska, so that wasn't hard. They seem to hold their moisture well, but shrink considerably if allowed to dry out, which I avoid. My neighbor bought some and they started to mold and then crumble and fall apart after a year or so. I'm guessing she didn't keep them in a cool enough place. So, I'd say with proper care they should last as long as 4 seasons. They do work very well and I assume it is because they don't dry out quickly. Also, I use a gallon ziplock as a mini-greenhouse and just blow a breath (CO2) into the bag once a day or so. Like others have said, these come in a heavy ziplock bag.
