WE COLLECTED AROUND 100 BOTTLES OF 100 PLUS BOTTLE AROUND THIS MONTH. THEN WE FULFILL THE BOTTLES WITH SAND .
THEN WE PUT ALL THE BOTTLES INTO EACH FLUSH IN THE TOILETS AROUND OUR SCHOOL. BY PUTTING THIS BOTTLE INTO THE FLUSH WE COULD SAVE THE USAGE OF WATER WHEN WE FLUSH AS THE BOTTLE DISPLACE SOME VOLUME OF WATER IN THOSE FLUSH .WHICH MEAN , THE MORE YOU PUT THE MORE VOLUME OF WATER YOU COULD SAVE.
THIS IS ONE OF THE EASIEST STEP ON HOW TO SAVE THE USAGE OF WATER IN OUR SCHOOL.
EASY RIGHT !!!!!
