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.
Origami leis are nice because you can use colored paper that follows the school colors, you can shape them into flowers, and they will last forever. If you are unable to make it to the graduation ceremony and lei the new graduate, then sending a flower bouquet is the best alternative. You can shop for the bouquet with either the schoolâs color-theme in mind or select flowers based on what you think the grad would like.
