Free Magnetic Periodic Chart or Tri-Color Triangle Highlighter

Here's a little freebie for that young scientist in the family -- actually he or she doesn't have to be that young, these could come in handy at all ages. Sigma-Aldrich® has released a Materials Science catalog, and to attract some interest they are giving away your choice of one of two items: a magnetic periodic table, or a tri-color highlighter in a triangular shape.

The highlighter will come in handy for students of all kinds, since they can highlight passages in different colors based on specific topics or emphasis. And for anyone with an interest in chemistry and science, a handy periodic chart will make a nice reference item to display.
