How to Make a Solar Oven from a Pizza Box

You can build an oven that cooks up to 200°F with a pizza box, tape, plastic wrap and aluminum foil. First, cut a flap into the lid of the pizza box. Cover the lid and the bottom of the box with aluminum foil. Seal your food inside the pizza box with plastic wrap and tape to create an airtight compartment. Finally, place the oven in direct sunlight.

the pizza box has good insulation properties and can take the heat. the plastic wrap should not actually touch the pizza, it's there to let in high energy IR and trap the low energy IR radiated back by the contents.

How is this any more of a "solar oven" than wrapping a piece of pizza in plastic wrap and leaving it in the sun?

Get your daily minimum requirement of aluminum and sundry industrial chemicals.
Get busy, liver.

You can not comprehend the size of the milky way. I even doubt that a human can understand much more than 1 km or maybe 10, but that:s it. Even though you may vizualize it by increasing scales, í consider these vizualisations not helpful, as you only show the scale between two objects that both are beyond comprehension. But you always encouter this kind of problems when trying to vizualize something as large as a galaxy. However, i really like the effect of switching off the milky way, that is a really cool effect, very impressive and really shows how large the void behind the curtain of the milky way really is. .

Last I checked, the limit of the observable universe is about 54 billion light years. That's about 4.6E24 miles, an incomprehensible distance. Our own galaxy, by comparison, is "only" about 125,000 light-years in diameter, or about 1.5E14 miles. Sounds really big on its own, and, by our scale, it is, but in the whole of the universe, it is less than a fly-speck. Talk about feeling insignificant.
