Crocheted bead red necklace

This is water, H2O... two molecules of hydrogen and one molecule of oxygen.
These plastic beads are part of an exhibit at the NY Hall of Science, where I work.

Borrowed 5 oxygen molecules and
crocheted red thread on top of them and came up with this necklace.

This was inspired by the book, Crochet Jewelry,
by Waejong Kim and Anna Pulvermakher.
