Imagine tossing a giant water droplet to a friend- this is what it feels like to hold a balloon-less water balloon. The outside of the giant droplet is smooth and it pops when thrown or dropped.
With this kit, you only need a few things from the kitchen to make balloon-free water balloons. The whole process takes about 20 minutes, including rummaging through your cabinets for utensils!
The kit comes with a set of thoughtful instructions and portioned amounts of Sodium Alginate and Calcium Lactate for the recipe. You'll also get a nice little box to keep the instructions in too!
The process shared in this kit is a well known culinary technique. There are chefs and creators around the world using spherification to make everything from delicate bubbles of fruit juice, to faux caviar, to edible water bottles. Here is a chef making faux caviar:
Funny enough, the two chemicals used in this process are pretty common. For instance, Calcium Lactate is a main ingredient in pickle juice and Sodium Alginate is used by Brown Seaweed to support its cell walls. I happen to think it even smells like the ocean!
When you place a spoonful of the Sodium Alginate solution into the Calcium Lactate bath, it is drawn into a spherical shape and develops a gel-like membrane. The membrane is a result of calcium atoms displacing sodium atoms from the sodium alginate. Our new bond has a higher charge creating cross-links between the chains of molecules, forming a gel.
Not only is this whole process plastic free, it's super safe for your friends and pets. Both of these chemicals have been studied on their own and combined. They have long been deemed safe and edible. The membrane created by these chemicals is resistant to breakdown by human digestive enzymes and alginates are classified as dietary fiber. Makes sense to me since it acts a lot like cellulose (fiber) in seaweed!
There are 7 simple steps that are included in the kit. Each step is clear and easy to read.
The whole process takes about 20 minutes. The perfect amount of time before the anticipation and heat start to melt the brain of any mad scientist. After a few minutes in the bath, the little ghost-like blobs are ready!
Inside is water! The outside is a gel-like membrane that is really satisfying to burst. Give it a try! You want to, right?!
I spent time fiddling with the recipe so I could get the instructions just right. Although I'm sure there's a more scientific way to calculate the best ratio of chemicals and duration of each step, I simply adjusted a variable a few times until I thought it was a little easier to manipulate. This is a work in progress so let me know if you have any suggestions.
In keeping with the simple packaging, I wanted to create a design for the box that didn't require stickers, as these usually have a plastic film. So, I'm simply laser etching the design onto a box. The laser removes the thin layer of ink and creates an almost screen printed look.
This project is part of a fun experiment where creators make smaller campaigns with a few guidelines to keep things lite. I whipped this project up in one weekend! Actually less, because I had another project in mind that didn't come together. Long story short, this was a snap, you should do it too!
