📝 Walkthrough

Overview

A couple rides a hot air balloon that is stuck in the clouds. Below are balloons, a candle, and a fan. The solved frame shows the balloon now rising with the couple happy and hearts, and the message "The view above is really wonderful!".

Difficulty: Easy
Estimated moves: 1

Step-by-Step Solution

Look at the options. A candle, a fan, and some loose balloons are below.

Do not use the fan or balloons. They will not lift the balloon.

Light the candle. Tap or light the candle beneath the balloon.

It heats up. The candle heats the air inside the balloon envelope. The hot air makes the balloon rise, and "The view above is really wonderful!" appears.

Strategy & Reasoning

A hot air balloon rises by heating the air inside. Lighting the candle provides the heat, making the balloon go up.

The name "hot air balloon" gives the mechanic away: it floats by warming the air inside the envelope. The fan would only blow the balloon around, and the loose balloons are unrelated decoration. Lighting the candle under the basket heats the air, the balloon becomes buoyant, and it climbs out of the clouds.

Why light the candle? A hot air balloon floats by heating the air inside its envelope, so the name itself gives the mechanic. The fan below would only blow the balloon around, and the loose balloons are unrelated decoration. Lighting the candle under the basket heats the air, the envelope becomes buoyant, and the balloon climbs out of the clouds. The couple riding it then enjoy the view from above. The puzzle is simply understanding that "hot air" requires a heat source — the candle.

It helps to remember how a real hot air balloon works: the envelope stays buoyant because the air inside is warmed, making it lighter than the cooler air outside. Without a flame, the balloon just hangs where it is, no matter how long you wait. The fan below looks like it could blow the balloon upward, but moving air does not change the balloon's own lift, and the loose balloons are unrelated props. Lighting the candle is the only action that heats the trapped air. Once the envelope warms, the couple aboard rises above the clouds, which is what the closing message celebrates.

Light the candle to heat the balloon's air; the fan and loose balloons do not lift it.

Lighting the candle lifts the balloon and the couple above the clouds.

The fan cannot lift the envelope because moving air does not change the balloon's buoyancy; only warming the air inside with a flame does that.
