Nappy Science

Today we had an experiment with Mrs M we needed nappys (different kinds) cups and bags. We ripped the nappy open and took all the cotton out and there were little tiny specs of polymer. We tipped the polymer into a cup and added water. Then we waited for about 10 seconds and it turned into this jelly stuff.
After that we poured some salt into the polymer and stirred it until it turned back to liquid.
