WATER BUBBLES
THE FUTURE OF WATER BOTTLES
Water bubbles are a biodegradable, edible, and safe alternative to water bottles! We hope to spread an innovation that could seriously decrease the plastic pollution in the ocean.
Why Water Bubbles?
Currently, there are 315 billion pounds of plastic waste in the ocean. This is a huge problem, because it strains wildlife, and pollutes a natural resource we so desperately rely on. Our project, "Water Bubbles", aims to help fix that. Our senior capstone project would be to create a biodegradable / edible water bottle, so that we can reduce the 46,000 pieces of plastic bottles that float in the ocean today. We feel this will be a great product on the market as our earth is rapidly deteriorating. There are many activists and conservationists who are pushing to save our planet and we feel this will be a great product to market towards them as they will love an alternative to plastic water bubbles that generate hundreds of tons of plastic each year.
What Is a Water Bubble?
A water bubble is a biodegradable and edible water bubble that is composed of sodium alginate (found in seaweed), and calcium lactate (found in baking powder). The two ingredients combine to undergo a process called reverse spherification. In other words, when the calcium lactate and water solution get dropped into the sodium alginate bath, the sodium alginate causes the solution to from a gel like shell around the water. This creates the "water bubble" as the calcium lactate shell forms in the shape of a sphere, creating a shell filled with water.

3D Printing Packaging
04/24/2019
To model our packaging, we used a 3D printer to create a small scale model of it. the material used in the 3D printer is corn-based and therefore is biodegradable and will not harm the environment. However we still need to work on finding a way to make the packaging on a much larger scale. To learn more about...
