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.
Best Answer: In true Hawaii custom, it is common to give a lei to someone of distinction. In this case, a graduation ceremony is quite a distinction, needless to say. Therefore the people you see recieving a lei at graduation outside of Hawaii likely have some sort of ties to Hawaii -- personal, family, or friends. Overall, you need to avoid the stereotype of lei's that tourists wear, it's not the same meaning at all. In true lei fashion, one never buys their own lei to wear on themselves as that is contrary to the whole meaning.
