Water balloons without plastic . A kit to make water balls that you can throw and even eat!
Imagine throwing a giant drop of water at a friend – this is what it feels like to hold a water balloon without a balloon. The outer part of the giant drop is smooth and explodes when it is thrown or falls.
With this kit, you just need some things from your kitchen to make them. It only takes about 20 minutes, including the search for the necessary materials!
The kit comes with a set of instructions and amounts of sodium alginate and calcium lactate from the recipe.
The process is a well-known culinary technique. There are chefs around the world who use spherification to do everything from delicate fruit juice bubbles, to fake caviar, to edible water bottles .
It’s funny, the two chemicals used in this process are quite common. For example, calcium lactate is a main ingredient in pickles and sodium alginate is used by brown seaweeds to maintain their cell walls. It even smells like the sea!
When a tablespoon of the sodium alginate solution is placed in the calcium lactate bath, a spherical shape is drawn and a gelatinous membrane develops.
This process is not only plastic free, but is super safe for children or pets. Both chemicals have been studied by themselves and combined. They have long been considered safe and edible. The membrane created by these chemicals is resistant to decomposition by human digestive enzymes and alginates are classified as dietary fiber.
There are 7 simple steps that are included in the kit. Each step is clear and easy to carry out.
This project is part of a fun experiment in which creators make smaller campaigns.
They were sold in their Kickstarter campaign .
