Good times.
As a youth, spitballs became a thing in the classroom.
One would use his tongue to roll a spitball, then wrap an elastic around a finger and thumb (think “slingshot”) and fire your spitball at another student via the elastic band.
My brother and I would practise in the basement. I recall we got that spitball going through seven or eight sheets of paper.
Good times.
