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,' they said on their crowdfunding page.

 

 

It is made using a mixture of sodium alginate, taken from brown algae, and calcium chloride.

The Ooho sphere has a double gelatinous membrane.

 

 

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. There is currently no retail price.
