Superabsorbent polymers for water are frequently polyelectrolytes. The swelling ratio of a superabsorbent polymer can reach the order of 1000:1. What are materials that absorb water Traditional Water Absorbing Materials Mention about the water absorbing material, you may think of many absorbing materials such as cotton, napkins, sponge, anhydrous calcium chloride, soda lime, allochroic silica gel or activated carbon. 9 Notes: The liquid absorbed can be water or an organic liquid.

The inspiration for this class (or "what I thought kids might do"): This book was a bit of a stretch, but I've always loved the page where Maisy is standing at her front door in her towel, dripping water and it's not easy to search for picture books that specifically include towels!įor one of the classes, I also showed this duck video and talked a little bit about how duck feathers don't get wet but the water just slides right off and why (the ducks have a special oil gland that they use to spread oil over their feathers to waterproof them). Water droppers (we also used baby-ibuprofen-type syringes) Water is an important solvent, so its unsurprising that there is a term specifically related to water absorption. Let's learn about things that absorb and things that repel liquid!
