Challenge for the Experts and a gesture of kindness from the Mighty Nations

Greetings from the Philippines,
I come from one of the poorest country in the world and is calling for the kind hearts of the mighty nations of the world who loves challenges and help out at the same time.The challenge would still be anything of your interest but would be focused more of the use of basic tools or the fabrication there of before the realization of the main product.
The main product must be preferably sourced out from recycled,re purposed,from dumpster or readily available from nature and must be of low carbon footprint.
The finished product will be posted to showing the authors the recipients and how their efforts made a difference in the lives of the poor nations although struggling yet inspired from the kindness of their brothers from the mighty nations.
May your goodwill be rewarded as expected.
