Many of the kids learn how to do this in elementary music.
You can possibly get a kid interested in learning real percussion.
You can play fun music, support the school, and THIS can be the group that plays at those "we need the band to do X," a week before your Winter Concert/UIL/etc.
Plenty of great resources for it too. And there are TEKS for beginner percussion.
The kids that don't want to deal with the noise will get schedule changed, and you'll be left with decent kids too, even if not too talented.
You can get your local Lowe's or Home Depot (or both) to donate 15-20 buckets each, and buy two bricks of the cheapest wood sticks possible to use.
