Genial
Tener un péndulo de Newton era un deseo de mi hijo, y estas navidades ha sido la ocasión perfecta. Había muchos modelos a elegir, y todos tenían algunas malas críticas que nos hicieron dudar en cual coger. Pero éste, ha sido todo un acierto. No es que dure mucho rato el movimiento ,pero a los padres, ya nos va bien que así sea..
