But you already know about this, because Fg is what normies call an object’s “weight,” and for a given volume, weight depends only on the density. Now, if you dropped these blocks in a lake, obviously the styrofoam would float and the steel would sink. So clearly it has something to do with density. What…

Our leaf blower testing process starts well before the actual tests, when we rope off a swath of grass and dump the same amount of leaves inside the boundary for every model. To have a reliable pile before every fall for the newest models, we usually start collecting our leaves a year or more ahead…

A low-heat burner that’s capable of maintaining a steady temperature when simmering liquids is ideal, so you don’t need to stir constantly to avoid scorching, say, tomato sauce or chocolate. They bake and broil evenly. Cakes and cookies emerge uniformly baked from multiple racks. And the broiler heats evenly while still getting…
