1. Introduction

We participated in the 17th Flow Dream Contest held in Toyohasi city.
We are the team of seven people. our team name is Meisei industries.
We made water that we could grab. I think that water to grab can reduce PET bottles, and Leading to global warming countermeasures.

2. About our production

We have prepared water and Sodium alginate and Calcium lactate. the working process, put 200 ml of water in a PET bottle, put sodium alginate therein, and shake the PET bottle. Then 800 ml of water in an aluminum bowl.

Add calcium lactate and mix. Then, water containing a mixture of sodium alginate and water is put into a ladle, and then put into water containing a mixture of calcium lactate and water. After a few moments, a film is formed and the water that can be grabbed is completed. We experimented with drinking water other than water. As a result, it was created as water that can be used for grab to water such as soda drink, tea, lemon tea, apple tea, corn potage, tomato juice, and sports drinks.

3. Conclusion

To stop global warming in recent years, it is important to reduce the number of plastic bottles.  I believe that this is one of the measures against global warming.
