The Digital Bits Science Labs are fun science experiments for young children. Kids, make sure you have an adult's permission before trying any of these science experiments.
Digital Bits Science Lab
Science Experiments for Kids, Parents and Teachers
Heat conduction with water, balloon and candle
Description:
This experiment shows how water can conduct and absorb heat.
Equipment needed:
Water
Balloons
A lit candle
The Digital Bits Science Lab Experiment:
Blow up a balloon. Hold it over the lit candle. Boom! The balloon explodes! The lit candle heated the balloon, weakened and melted it, and the balloon exploded.
Now take another balloon, and fill it halfway with water.
Hold that same balloon over the candle. Do you think the balloon will explode, splashing water everywhere?
Nope.
You can have the candle flame actually touch the balloon, and the balloon won’t break!
The water in the balloon is absorbing the heat from the candle. The balloon conducts heat very well, so the candle flame transfers to the water without harming the balloon.

Hey! This is a pretty cool science lab i like the way you told me that you will need to fill it up with water.
Yup, the “fill it up with water” is pretty important to the success of the lab.
that is awsome
i was looking for a water balloon an google and got this! it is pretty kool though:)
this looks like a really cool expirement. Try it some time!
awsome i will totally do that
cool….
thank you for posting this .
