A recycling project by team 7UP at Sơn Ca Kindergarten (Hanoi), 17 October 2026

An empty milk carton.Usually… it ends up in the bin.

But what if you lay it down…cut out two little windows

…add bottle caps for wheels…and let tiny hands do the rest

Turning waste – into something lovely

On the morning of 17 October 2026, about 140 children of Sơn Ca Kindergarten did just that with team 7UP.

Gathered

7 people, 41 days, every box of fundraising cake, every milk carton washed clean.

Thank you 7UP

Each bottle cap is one team member. Flip a cap and you'll find a milk carton holding a thank-you note.

Our 41 days

Behind the scenes

Selling cakes, visiting the school, manning the lobby booth, sitting on the floor packing gifts late into the night — and one well-earned party.

21/9 – 9/10

Fundraising: durian cakes

We took turns selling durian cakes over 6 rounds of orders and kept the cash book every day, so we could fund 100% of the Little Creators' Workshop ourselves.

    What did the school & the children say?

    A team member hands the S-shaped map made of milk cartons to a teacher

    The board & teachers

    They valued the workshop very highly: a fun, hands-on activity that made the lesson about protecting the environment concrete. The school appreciated the team's care and loved the S-shaped map and the recycled table and chairs.

    Two girls proudly hold up the milk-carton cars they just made, beaming beside the workshop table

    140 children

    They joined in with huge excitement: painting with their own hands, building toy cars and having fun putting the S-shaped map together.

    — from the feedback recorded in the team's final report

    what team 7UP learned after 41 days

    “The value of a community project doesn't have to lie in its size. For Nhỏ Mà Xanh, it was old materials getting one more use, children getting one more meaningful experience, and everyone involved realising they can start living green with very small things.”
    — from the project's final report
    “The most precious thing isn't material at all — it's the genuine affection and the wish to keep our homeland green, planted like a seed in every child's heart.”
    — team 7UP, in the final report
    “Maybe one day, while we're still students at FPT, a Nhỏ Mà Xanh 2 will be born and keep bringing recycling workshops to little children.”
    — team 7UP, in the final report

    “Nhỏ Mà Xanh” isn't just a project — it's the beginning of a journey of planting green seeds, one we will carry with us wherever we go.
