A few random thoughts...
I used to carry a little emergency fire extinguisher to many events and activities. Great for cooling all kinds of emergencies.
Is it possible to develop a drinking habit and carry a heavy stein or mug everywhere?
Ongoing science projects, history dioramas, other constructed projects can cover a multitude of raw material being carried back and forth.
Take up the flute. There is a wonderful innocuous looking clear lexan tube flute that is rather impervious to the dings and knocks of life. Can't remember where I saw that.
Perpetually carry a bouquet of NOT thornless roses.....
Clipboard!
Carry your spike shoes slung over your shoulder...
Baseball bat and ball, hockey stick, lacrosse stick, set of steel horseshoes and stakes, golfclubs, bowling ball, tennis racquette,
hive of bees or hornet nest for show and tell...
Join the drama club, tools for scenery might have to be carried back and forth.
Astronomy club, telescope can be carted back and forth? Another ongoing project building a home made scope of rather durable goods.
Chess club. Work on your own set of pieces like in Shawshank Redemption, using a rock hammer? Or just carry rock, bronze or glass set with considerable heft.
Lunch box, custom job along similar lines to the clipboard above or to the vandal-proff mailboxes.
