Product Description

Superabsorbent polymers (SAP) (also called slush powder) are polymers that can absorb and retain extremely large amounts of a liquid relative to their own mass.

SAP may absorb 500 times its weight (from 30-60 times its own volume) and can become up to 99.9% liquid, but when put into a 0.9% saline solution, the absorbency drops to maybe 50 times its weight.

The largest use of SAP is found in personal disposable hygiene products, such as baby diapers, adult protective underwear and sanitary napkins. SAP is also used for blocking water penetration in underground power or communications cable, horticultural water retention agents, control of spill and waste aqueous fluid, artificial snow for motion picture and stage production. The first commercial use was in 1978 for use in feminine napkins in Japan and disposable bed liners for nursing home patients in the USA.

Order process was flawless and arrived very very quickly. The only bad thing was no instructions. Would have liked to have the noted or known ratios of water to polymer. Internet recipes are all over the place. Thus you are left with trial and error to determine the ratio for best performance.

This is absolutely great for the "Making Water Disappear" magic trick. You really only need just a little bit, like 1/2 teas. I think this bag held about 3 tablespoons. We had enough to practice the trick multiple times, do the show, and still had some left over.

It does absorb. I have to use it more but for now I only did a test. You just have to add little by little and give it time to react before adding more each time. I find a little is more and a little goes a long way. That is why the package is so small. It's about the size of a pack of Kool Aid so remember A LITTLE GOES A LONG WAY.

This is an amazing product -- just a little bit in a ton of water makes a ton of gelatenous product that you can use in your garden or in houseplants to keep them more hydrated!

Mix 1tsp with a quart of water to add to potting soil to help soil hold water longer. IMPORTANT*** do not add Epsom Salts to the water, the crystals will not absorb any water.

This product is good and I don't find any issues with it. I've started using this product very recently and no complaints so far.
