What is rainbow loom?

The Rainbow Loom is a long plastic peg board to put small silicon rubber bands on in various patterns. These rubber bands are then looped together, one to the next, using a tool (hook) or crochet hook. After all the loops are connected, you can take all the bands off the loom and it is a friendship bracelet. The Rainbow Loom can also be used to make necklaces, charms, headbands, cell phone pouches and action figures.
