Water is a basic necessity, we require a daily intake of 3-5 liters. Almost in every country water is sold in plastic bottles, which are terrible for the environment. yet, only few of us re-use the same bottle for days. what if we do not need to sell water in plastic containers ? instead it can be sold in an edible gel type globe.
I came across this innovation a few months back when i was randomly watching some tech videos. The pioneer of this idea are a group of engineers from Skipping Rocks Lab. Water is stored in the globe and the outer shell of the sphere/globe is made from an algae which is edible and hence biodegradable. The water can be consumed either by tearing a hole in the sachet or eating the sachet itself.
The basic chemistry of the package:
The main ingredients of this membrane are 1. Sodium Alginate, usually derived from seaweed and 2. calcium chloride. There are several DIY videos on YouTube through which you can create these spheres yourself. however, the team from Skipping Rocks Lab uses a tweaked version of these technology to create tougher larger sphere.
