Young Scientists at Play: Polymer Play – Making Snow

Did you know that up market nappies contain polymer balls?  They exploit the water absorbing qualities in order to absorb urine.  These are made from a similar polymer to water beads and are the chemical that is used to make fake snow.  This polymer is also used for its  water absorbing properties in gel flood bags to contain a flow of water.…

Continuing our fun with polymers, I thought I would introduce the little ones to a very different type of polymer - the water bead.  These are basically polymers which when in their dried state will absorb copious amounts of water and swell from the size of a tiny bead to the size of a marble.  I…
