COMPETITIONS Comp

Bring the frosty feeling of Antarctica to your home with a flurry of polymer snow. Just add water to these super absorbant polymers and watch the hydrophilic (water-loving) molecules expand. The molecules have a high sodium content, which attracts water into the polymer. When the water evaporates, the polymers can be reused by simply adding water again.

Mad About Science (www.madaboutscience.com.au) has sent us lots of polymer snow test tubes for Double Helix readers to win! Enter this competition by sending us a drawing of your favourite Antarctic animal. (HINT: don’t get confused with Arctic animals!)
