Splitting Procedure

& Explanation

Materials:

2 x lemonade or coke bottles,                                   

2 x  large buckets                                                         

2 x normal shaped balloons

Hot water

Cold water

1. 
   First pour the hot water into 1 of the buckets about half way, do the same with the cold water and the other bucket.
2. Now strap the balloons onto the mouths of the bottles.
3. Now to start the experiment make the bottles completely immersed in the water.
4. Now observe the two different balloons. The balloon in the hot water will start to rise and the other won’t. The balloon that is in the cold water might start to shrivel.

Why It Happens

It is caused by the air particles. In the cold water they are in a state of inertia. But in the hot water they need to expand. They move around looking for more space causing them to move into the balloon. When they expand, the balloon expands.
