Blowing out birthday candles vs. blowing on a campfire to make it bigger — same breath, opposite results — plus cupping your hands around a match in the wind. A jar over a tealight on a windowsill is a thing a kid can literally do at home.

- Name the three things every fire needs at the same time — what happens if you take one away?
- Why might blowing on a fire sometimes make it bigger instead of putting it out?
