P20 - How to keep paper tissue dry under water?

Inu asked mummy its been long time we did an experiment, can we do one today. How can I refuse such a cute request, so I started the discussion. I asked her, 'What will happen to a paper tissue, if I put it in water.' She replied, 'It will be wet.' Then I asked her, 'Can you think of a way to keep the tissue dry in water.' She was clueless and asked me to start the experiment. 

What you Need:
        - Paper tissue
        - Bucket or big container full of water
        - Glass (preferably transparent)

I asked her to try with paper tissue kept in a glass. First, she scrunch the paper tissue inside the glass and put the glass inside the water. The tissue gets wet as water entered the glass. Then I asked her what if we turn the glass upside down. She did the glass upside down and put it straight into the water container. During this trial we need to make sure we have enough paper tissue inside the glass so that it wont fall out when you turn the glass upside down. She pulled the glass out to see if the paper tissue was wet or not. 

She was very surprised and happy that the paper tissue was dry. The glass was filled with paper tissue and air. When we pushed it into the water, air did not got any space to go. As air is lighter than the water so it stayed up and kept the paper tissue dry. 

Next, I asked her to repeat the experiment with glass little tilted in one side. This time the air escaped the glass making room for water to go up. So, the paper tissue get wet this time. 

I hope you enjoyed this experiment. If you repeat it please do let us know by leaving a comment. You can also share the post with your friends. Also, follow my blog to get updates about all the activities we do.
