Here's what happened: The powder and the water turned into a jelly solid. We watched a physical reaction take place. We've witnessed chemical reactions before where two chemicals come together to create a new chemical, like baking soda and vinegar. In today's experiment, the polymer simply soaked up the water and turned into a jelly like substance. No new chemicals were created so we just witnessed a physical change.
Turns out we were able to undo the physical reaction we witnessed with a little bit of salt. If you eat a lot of salt, chances are you're mouth is going to be dry and you will want a glass of water. When you add salt to the polymer water mixture the salt starts to suck up the water and release it from the polymer. Super cool. The title of this experiment comes from DIAPERS. Gross? Not really. Polymer powder is found in diapers and that what magically soaks up all the liquid.
Try putting a diaper in a pool!
