CamelBak make some bags that have built-in water supply and a good amount of storage.
Manufacturing companys who make the bag supply air in the bag in the result of them not going stale
get a plasic bag and fill it with water close the bag tape the bag zipper to the bag cover the bag with duktape do not miss a spot
make sure you keep the water clean. do not use tap water straight from the tap because of the chemicals in it. put a supply in a large container and allow to 'sit' for sevearal days. acclimate new fish to the water by putting the bag with in the water then allow to float for several minutes so temperature balances then release the fish from the bag. don't overfeed them.
Osmotic pressure. The concentration in the bag is greater than outside the bag. Sugar molecules cannot pass thru the bag but water can. To try to create the same concentration inside and outside the bag water moves into the bag to dilute the solution inside the bag. This extra water now in the bag causes the liquid to move up the straw.
If you place a dialysis bag filled with water into a beaker of water, there will be no significant change in the dialysis bag's contents, as both are isotonic. Since there is no concentration gradient for water to move across the semi-permeable membrane of the dialysis bag, osmosis will not occur. The bag will remain filled with water, and the surrounding water in the beaker will remain at the same level. However, if the dialysis bag contains solutes that are not present in the beaker, osmosis may occur, leading to a change in the bag's volume.
you already have it built into your bag!!!
Water in a black bag will heat up faster than water in a white bag. This is because black absorbs more heat than white, so the black bag will absorb more sunlight and transfer that heat to the water more efficiently.
Only the water can enter into the bag and leave the bag, the tea leaves can not leave the bag.
If a dialysis bag filled with sucrose is placed in distilled water, water will move into the bag through osmosis, as the concentration of sucrose inside the bag is higher than that of the distilled water outside. This influx of water will cause the bag to swell and potentially burst if the pressure exceeds the bag's capacity. Since sucrose molecules cannot pass through the dialysis membrane, they will remain inside the bag, creating a concentration gradient that drives the osmotic movement of water.
A MP3 player is a useful gift for a runner and there are models on the market that are specially designed for runners. Another nice gift idea is a bag filled with items like energy bars, drinks, sweat bands and a running log.

No. Roots wrapped in plastic bag cannot absorb water.
