Eco Solar Cooker is a cooking utensil invented by Earth Cardboard. Using 
silver-colored cardboard, it collects the sun's heat and light. The cooker is 
convenient for outdoor cooking such as camping and barbecue and useful as a 
disaster kit.

Eco Solar Cooker:
- is handy because it is lightweight and small before being assembled.
- is disposed of easily.
- can make small donuts.
- can cook rice.

It is a very convenient item but water-sensitive because it is made of 
cardboard. Therefore, Earth Cardboard applied a varnish coating to Eco Solar 
Cooker to make it water repellent. Eco Solar Cooker can be used even in case of 
light rain or splashing by a child playing with a water gun.
