Safety was my first concern in designing the Solar Funnel Cooker,
then came low cost and effectiveness. But any time you have
heat you need to take some precautions.
-The cooking vessel (jar) is going to get hot, else
the food inside won't cook. Let the jar cool a bit
before opening. Handle only with gloves or tongs.
-Always wear dark glasses to protect from the sun's rays.
We naturally squint, but sunglasses are important.
-Keep the plastic bag away from children and away from nose
and mouth to avoid any possibility of suffocation.
