Talk story with almost any elementary or middle school student on Oahu these days and chances are slime will enter the discussion at some point.

Interest in homemade slime, with multipurpose white glue as a key ingredient, has surged over the past year thanks to viral internet posts. A search for the hashtag “#slime” on Instagram returns more than 2.5 million results, while the phrase “DIY slime” turns up nearly 7 million YouTube videos on the subject.

Making slime can even make you famous in 2017: Oahu resident Hali‘a Beamer, 12, is a budding social media celebrity with nearly 3 million fans on the app Musical.ly, but she’s also racked up nearly 4 million YouTube views with a series of videos documenting her love for the stuff.

While some recipes posted online call for sodium tetra borate hexahydrate (better known by the brand name Borax), experts caution against letting kids handle an irritant that can cause chemical burns after prolonged contact. Instead, look for recipes that use less-toxic ingredients like contact lens solution, cornstarch, vegetable oil and hair conditioner.

Office Depot will host a free hands-on workshop in making slime from noon to 3 p.m. Saturday at its Kalihi store (1505 Dillingham Blvd.) and its Kakaako Office Max location (770 Ala Moana Blvd.).
