Can superabsorbent polymer crystals absorb any other liquids besides water?

In this experiment,determine if this crystal can absorbother liquids byadding them to orange juice, vegetable oil, milk, rubbing alcohol, vinegar, and club soda.A hydrogel crystal (sometimes called a "disappearing crystal," "water crystal," or"superabsorbent gel,") is a long chain of molecules bonded together to form a superabsorbent polymerthat does not dissolve,but forms a gel when placed in water. Itis often used in gardening, landscaping, and farmingas a way of retaining moisture. The crystal is made up almost entirely of water. As the crystalsdry, water is slowly released to the soil. Some of these crystals can soak up as much as 500 times their weight in water! This superabsorbent characteristic makes hydrogel crystals useful in solvingwater conservation issues.Safety:The investigator should not ingest the crystals or drink the liquids associated with the activity. The crystals used in the project are extremely slippery when spilled. Never flush or pour these crystals down the drain, as crystal swelling could possibly clog drainpipes.
