When you are extremely bored in class, a very entertaining activity is to pour a nice sized glob of glue (preferably Elmers white glue) onto your hands. Then when you rub your hands together, the glue will become solid and is then fun to peel off.
This activity can be an entertaining activity to be used anywhere from a fifteen minute public speaker, to a two hour lecture.
It is not harmful to your health in anyway.
Gorilla glue and other extremely adhesive glues have not yet been tested, so please use caution when experimenting.
"Dude, how did you manage to stay awake? That guy was so boring!"
