Create and explore an imaginary lab under the sea with Magnetivity Magnetic Building Play Set Underwater Adventure! Magnetivity encourages kids to experiment, explore, and imagine by inspiring them to design and build their own unique worlds! The 10 double-sided panels with artwork on both sides magnetically attach in different combinations, so kids can build new designs for their own underwater lab and explore with the submarine every time they play. The 41 included magnetic accessories stick to the panels and to the three magnetic wooden play figures (including an underwater robot!) with stands, inspiring open-ended, hands-on exploration and play! All Magnetivity panels are compatible.
