The ‘Ooho!’ is a squidgy globe filled with water that could change the way we drink water. The bubble-like spheres were first invented by a trio of engineers.

The Ooho sphere has a double gelatinous membrane. It is made using a mixture of sodium alginate, taken from brown algae, and calcium chloride. The spheres are created using gelification – a technique used in cooking to turn liquids into gel by adding an edible gelling agent.

Edible packaging labels can also be added to the Ooho, between the two layers, without adhesive. The engineers said their ‘mission is to make packaging waste disappear’.  Ooho! is a sustainable packaging alternative to plastic bottles and cups, made from a seaweed extract. It is entirely biodegradable and so natural you can actually eat it.

The spheres are created using gelification – a technique used in cooking to turn liquids into gel by adding an edible gelling agent. The engineers are now raising around $500,000 (£400,000) so that they can bring their product to market. Each globule contains nine ounces (250ml) of water.  The spheres cost approximately 2 cents (less than a penny) a unit to make.
