Add science discovery and a place for experiments to any tabletop or storage unit. The Tabletop Discovery Lab includes two sections with clear acrylic covers and coin locks to allow teachers to place science or other items inside for children to view without touching. The open sections on each end have a removable divider. The two covered sections are 3-1/4"H inside x 9" x 11-1/2". The open sections are 4"H x 5-1/4" x 11-1/2" and expand to 10-3/4"W with the dividers removed.
