NOTE: 1  Gasses react more rapidly with moist rather than dry litmus. 2  Gasses change the color of litmus paper over its entire exposed surface, not just at the edges because they make contact over the entire surface. 3  The neutral gasses nitrogen and oxygen do not affect the color of either red or blue litmus.
The tradition of giving leis to graduates has now spread to the mainland. Many graduation leis at stateside schools are designed to reflect school spirit by incorporating flowers, yarn, ribbons or other materials in the graduate's school colors.
This is common for a birthday and a graduation celebration. Leis made with leaves from a ti (pronounced tee) plant are considered to bring good luck and ward off evil spirits. DO NOT refuse a lei when offered one. This is considered to be disrespectful. DO NOT wear a lei you intend to give to someone else.
