(Boat)tle / A PET design for poor children

Plastic bottles are recyclable.

But, due to the lack of technologies, they are either burnt or buried under the ground
thus leading to environmental disasters in the third world countries.

When burning the plastic bottles, not only atmospheric pollution happens,
but also carcinogens break out.

If buried, it takes about 100 years for the bottles to completely decay.

However, if we produce these plastic bottles in a different way,
they can become good materials.

Those children without toys in the third world countries can make a quality boat
using (boat)tles and a toy castle.
