In high school my three-person team turned a hatbox and some tinfoil into a little parabolic dish just strong enough for sunlight to toast a full size marshmallow placed at its focus.

The whole class went outside to watch the teacher eat the marshmallow. It was overcast and drizzling. Nevertheless, the marshmallow was lightly toasted.

PRAISE THE SUN! 🙌🌞🙌
