Fonctionnement - Parabolic solar cooker

Always use sunglasses to protect your eyes!

Fix the clamp on a stand (tripod, table edge) and squeeze in the tip of the umbrella.

To find the ideal orientation of the oven, place the palm of your hand about 20 cm below the handle. The shadow of the handle should "reflect" on your hand.

Put some food (egg, tomato) and a little bit of water in the box and close the lid. For a hard boiled egg, the cooking time is a little bit more than an hour.

The oven works best when the sun is clear and strong (not when it's a bit misty) and around noon. The temperature in the box can reach over 90ºC.
