'G' is for Glue


'G' is for Glue

Garretta loves her granny,
Who now has moved away.
Garretta used to see her
At least three times a day.

She wants to send a greeting
And has no time to waste.
Garretta finds her scissors,
Some paper and some paste.

She wants the card sent quickly—
But runs right out of glue.
Can she find some sticky stuff?
What will Garretta do?


Why does Garretta use milk to make glue?

Milk has a protein in it called casein (KAY-seen). When vinegar is added to the milk, thick white lumps form that are mostly casein. The casein is attracted to the fibers in the paper, causing them to stick together. This bond strengthens as the glue hardens.
