Re: “Helping flowers last longer”

Volume 94, Issue 12
Reader Janet Seymour appreciated February’s Periodic Graphics and its tips for ensuring the longevity of bouquets.
Always wondered why flowers last much longer if in a vase of lemonade. Sugars and acidified.

Editor’s note: To assist educators, C&EN and ACS released an infographic illustrating new National Fire Protection Association guidance for conducting demonstrations and experiments, as well as a video showing how to conduct flame tests using aqueous salt solutions. The resources are available at cenm.ag/labdemo.
