NEEDED: Tennis Ball Cutter!

I am looking for a parent to pick up a tub of tennis balls and cut a slit in each. We use these for the bottoms of our first grade chairs.  (They keep our room very quiet!!)  See  picture below.  Your child would not be able to carry the tub of tennis balls home on the bus, so you would need to pick them up here at school. I do not need these by any certain time.

Please contact me by commenting on this post, email, note or phone call if you would be interested in helping with this project!  Our ears would be very appreciative!
