Hot-Air Balloon

How it works

• Heat under its mouth warms the air inside, and warm air lifts it. As it cools, it sinks.
• Heat comes from a candle below it, a heat lamp or rocket exhaust. The closer the heat, the more it lifts.
• It hovers where its warmth just holds its weight, higher when light and lower with a heavy load.
• Pins and flames do not pop it, and wind blows it about.

Tips

• Put the heat right under the mouth.
• Load the basket from the side. A ball dropped from above bounces off the envelope.
