======Fireproof Balloon====== **Materials: **{{$demo.materials_description}}\\ **Difficulty: **{{$demo.difficulty_description}}\\ **Safety: **{{$demo.safety_description}}\\ \\ **Categories:** {{$demo.categories}} \\ **Alternative titles:** Fire Water Balloon ====Summary==== {{$demo.summary}} ====Procedure==== - Blow up one balloon with air only and tie it off. - Light a tea light candle or small candle with adult supervision. - Hold the air-filled balloon carefully over the flame and observe—it pops quickly. - Fill a second balloon with some cold water, then blow it up and tie it off. - Slowly lower the water-filled balloon toward the flame. Observe that it does not pop. ====Links==== Fireproof Balloon Science Experiment - Kids Fun Science: {{youtube>JO6X6K7zRnQ?}}\\ Fire Water Balloon - Sick Science!: {{youtube>qeDZQ9-gsjY?}}\\ 📄 Fireproof Balloon - Steve Spangler: [[https://stevespangler.com/experiments/fire-water-balloon/]]\\ ====Variations==== None ====Safety Precautions==== * Adult supervision required—this experiment involves open flames. * Keep hair, loose clothing, and flammable materials away from the flame. * Perform over a tray or sink to contain spills if the balloon bursts. * Do not hold the balloon too close to your face when lowering it over the flame. ====Questions to Consider==== * Why does the air-only balloon pop so quickly? * How does the water prevent the balloon from popping immediately? * What other substances might absorb heat like water? * How does this experiment demonstrate the concept of heat transfer?
