Experiment Update

This is an overdue update but as I could not purchase and find any recyclable antifreeze, my hypothesis of the experiment has changed and become "That Antifreeze does have an effect on the environment"

As the days went by....

During the first 18 days of growing the grass, the colour was luscious green and tended to stay like that. After the antifreeze was poured, gradually in the 6 days, the colour began to slowly change. First the top bits of the grass turned into a yellowish colour. Then the yellow faded into something much lighter and more of the green lucious coloure turned into a mucky light green. The grass began to fall and observations of the grass slowly deteriorating was made.
