Why Doesn't This Balloon Pop? Amazing Science Experiment | balloon vs fire.

[00:00:00]Everyone knows balloons pop when they touch fire. Look.

[00:00:08]>> Then why isn't this balloon popping?

[00:00:10]>> Well, look at the tablet. The water inside is absorbing the heat, protecting the rubber.

[00:00:17]Today, we're solving this science mystery.

[00:00:22]>> [crying and laughter] >> Hi everyone. I'm Dad.

[00:00:27]>> I'm Swarali.

[00:00:28]Fire experiments need adult supervision.

[00:00:32]>> We have two balloons for today's experiment.

[00:00:35]This balloon contains only air.

[00:00:39]And this balloon contains water.

[00:00:44]>> I think both balloons will pop.

[00:00:47]>> Let's test your prediction.

[00:00:50]First, let's try the air balloon.

[00:00:54]>> Goodbye, balloon. See you later. Okay, let's see what happens.

[00:01:02]Whoa, that happened so fast.

[00:01:07]>> But, why did it burst? The flame heats the balloon's rubber.

[00:01:12]The hot rubber becomes weaker.

[00:01:16]Then the pressure makes it burst.

[00:01:21]>> So, heat caused the balloon to pop.

[00:01:23]>> Now, let's test the water balloon.

[00:01:27]>> This one looks much heavier.

[00:01:30]3 2 1, let's go.

[00:01:36]Wait, why isn't it bursting?

[00:01:39]>> Look carefully at what's happening.

[00:01:42]>> The balloon is actually surviving.

[00:01:45]>> Exactly.

[00:01:47]Heat is still entering the balloon.

[00:01:52]But, the water absorbs that heat.

[00:01:55]>> So, the water protects the balloon.

[00:01:59]>> Exactly, that's the secret.

[00:02:02]This happens in everyday life, too. Look at the water cycle. Cars use water to stay cool.

[00:02:10]Firefighters use water for the same reason. Power plants depend on cooling systems, too.

[00:02:16]One simple change made all the difference.

[00:02:19]>> Science is amazing and fun.
