Sand

 is a line of supplements sold by Griffin and Freddie in iMLM. It is part of a multi-level marketing pyramid scheme.

Description
Sand products claim to give benefits such as calming people down, giving people courage and increasing people's sensitivity. However, the sand is later revealed to be fish food that simply acts as a placebo.

According to Griffin, Sand contains antioxidants, superfoods and organic mood boosters. When put in water, it "sands away the rough parts." He also claims that without calm sand, he would probably drive his motorcycle off a bridge.

There are various types of sand, such as
 * Calm Sand: Used by Griffin (supposedly) and Carly
 * Brave Sand: Used by Freddie before his serious talk with Millicent
 * Sensitive Sand: Used by Spencer
 * Happy Sand: Offered to Harper

History
Sand appeared in the episode iMLM. It is part of a scam run by Griffin, who re-connected with Carly to promote Sand.

After experiencing some of the "benefits", Freddie becomes a Sandbassador. He spends his entire life savings of $4000 on Sand inventory, which he planned to promote on an iCarly webcast. However, the webcast is cut short when Harper reveals that Sand is actually fish food.
