 COMBUSTION AND FLAME

“Heating water in a paper pan!”, It is not April fools' Day. How can anyone heat water in paper pan? Nina  was getting agitated. Her brother was always trying to fool her. He will not succeed this time, thought  Nina. OK, if you succeed, I will give you my favourite pen that you have been eyeing for long. But if you lose, you  will have to give me your new game set, challenged Nina. 

Little did she know that very soon she was going to lose her favourite pen. This time her brother was right. 

You can heat water in a paper pan. Why don't you also try it out and watch your friends' eyes popping out  with disbelief.

You will need:candle, matchbox, A4 size paper sheet, a plastic packet, water, cloth for cleaning in case water spills.

What to do: 

Measure one inch on all four sides of your paper. Mark with pencil. Fold the edges of the paper to form  sides of an inch high. Fasten the corners with paper clips. Pour some water in the paper pan. Hold this  paper pan over a candle flame.  After some time, ask one of your friends to dip finger into the water in the pan. How does it feel? Does it  feel warm? 

Now repeat the same experiment with a plastic packet instead of a paper pan. Does the plastic burn?  Does the water get heated?
