 MICRO ORGANISM FRIEND AND FOE

“My tummy is absolutely full !" declared Vijay putting away his plate. They had just finished having lunch  at Raghav's Place.

“What do we do with the left over food aunty?" asked Nupur while cleaning the dining table.

“Why don't you save them for a special party next week?" Suggested Raghav's mother with a mischievous  smile.

“Another party”? thought Aditya. "It is too good to be true". He loved food. “Why not aunty. Same place.  Same time. Right?” added Aditya.

A  week  later  there  was  an  unusual  excitement  in  the  air. All  the  children  got  together  promptly  at  Raghav's house. "Aunty, you had promised us another party today. Didn't you?" enquired Aditya. “Yes, a  special Mouldy Party, come see for yourselves" said aunty. Nupur and Vijay were eager to know how their  left over food had transformed in one week. 

If you have warm feelings for the fungi, you would love the mouldy party too. Do you want to know how    did they set it? You will need :Six empty clean glass jars, magnifying glass, food samples.
