The Invincible Balloon Experiment - Transcript
I’ll like to call this experiment the invincible balloon; all you need is a candle, some matches, a couple of balloons and some water, so let’s get going.
First of all we just light our candle and get that lit up, so I’ve candle ready. So when a balloon goes up against the candle it seems like there can only be one winner, so blow up one of your balloons, tie a little knot on that and then if I bring this balloon down to the candle you probable have a good idea about how this is going to work out…your balloon doesn’t survive.
So that balloon wasn’t invincible, but this is where the science of it comes in, so we’re going to light our next; we light the candle again, it does go with that saying you need to a sane and sensible adult to help out with this kind of stuff, but this one going to do one thing slightly different, so instead of putting the balloon straight on top we going to use a little bit of water first.
So this is the trick event, pure a little of water in your balloon, make a bit of mess as well, blow the balloon up just as before; I mean this time inside your balloon there’s a little layer or water, tie it up and then this time you’re going to slowly pull the balloon down on top of the candle, giving you every chance to hot.
So that is how you make an invincible balloon, on the bottom you can hopefully see a little bit but the important thing is what’s going on, what’s doing that; you might be thinking hopefully, well.
The reason is the water inside is dissipating the heat, the flames is obviously hot, it warms up the water so instead of melting the balloon it warms up the water, the water can now move that heat away so it doesn’t gets so hoe that it melts the balloon and that’s what makes your balloon invincible.
Give it a go and let me know how you get on.
