you can make a homemade indicator using purple cabbage juice. all you have to do is steam the cabbage, strain it and voila! the juice is a perfect acid-base indicator.

try using it on vinegar and liquid soap to determine what colour it changes into in different media. then you can use it on just about anything! record all your observations and use in your project

all the best!

The Newtons and friends were taking tea
Beneath the boughs of an apple tree,
When a falling fruit landed on the
Head of the head of the family.
Mrs. Newton cried, 'Well deary me!
That could've caused an injury'.
But clever Isaac alone could see,
The situation's true gravity.
