Question

Anand found that balloons rubbed with his sweater did not stick to the walls of his bathroom where he had just taken taken a bath with hot water. Give reasons

Answer 1

Possible factors

Possible factors in the balloon sticking are:

HumidityBalloon materialTemperature of balloonInflation of balloonRubbing materialSticking materialMaterialsBalloonsWool, clothes, and other things to rub against the balloonStringMaterials to stick against (usually parts of the room)Clock or stopwatch

(Note that static electricity experiments work the best on dry days. If it is rainy or damp outside, it is possible that things will not work very well.)

Experiment with sticking to different materialsRub a balloon some wool or your shirt.Then try to stick the balloon to different materials--like the wall, a door, the blackboard.Make a list of the materials and how well the balloon sticks.Draw some conclusions about the best and worst types of materials to stick to.Experiment on materials to rub onRub a balloon with different materials to see which works best for sticking it to the wall.Make a list of materials and how well they work for creating static electricity.Draw some conclusions and try to explain the reasons.Experiment with length of timeUse a clock to measure how long the balloon will stick to an object.Try this several days apart to see the effect that weather or humidity has on the length.Make a chart listing the time and the weather.Draw some conclusions.Experiment with two balloonsTie two balloons to pieces of string.Rub each balloon with the same material to charge it.Hold the string and let the balloons get close.Do they attract or repel? Why? Explain the reasons for what happens.Summary

There are a number of experiments you can do concerning static electricity effects on a balloon.
