Glue tin cans to a lazy susan for the arts and crafts table. You could make it twist and put it in the middle of a table with four students. Then they could like push it, when they needed something on the other side.
A twist on crate seating. The pull out drawers offer storage space. Can also use with child sitting on floor & turn crate seating to side as flat surface or if crate does not have holes instead solid surface use like a drum etc.
