I had a whole bunch of balls that the kids just threw around the daycare.. We needed a purpose for them, so I made colour tubes! I went to the hardware store and picked up these bends I think for plumbing and strapped them to the wall in our discovery area. I then painted them colours to match the balls and placed a container underneath to catch them. It works amazingly! The kids love it! And so do i … no more balls being thrown around.
