Abstract: A seesaw having an elongated planar member assembly, an axle assembly, and a ratchet-and-pawl assembly. The planar member assembly includes an elongated planar member. The axle assembly includes an axle member, an elongated radial extension, and a pair of wheels. The extension member extends radially between, and is coupled to, the axle member and the planar member. The pair of wheels is coupled to the axle member with one wheel disposed on each side of the planar member. The ratchet-and-pawl assembly includes a toothed gear, which is coupled to the axle member, and a pair of pawl assemblies. Each pawl assembly has a pawl member coupled to the planar member and structured to engage the toothed gear.
