Ooho spheres are created by dipping frozen liquid balls into an algae mixture that forms a membrane around the ice. The ice melts into liquid water and membrane, which is edible and biodegradable, forming a watertight seal around it. To consume the liquid, you can either bite into the tasteless membrane. You could also sip it out or eat the entire ball, membrane and all.

But with the rebrand, Notpla has focused on sustainable packaging that is a bit sturdier. Notpla started making seaweed-coated food packaging. The packaging is made from seaweed and other plants, making it biodegradable. It is designed for liquids and is biodegradable from four to six weeks.
