bueno, igual como la imagen. Muy buen artículo, es exactamente igual que las imágenes, además de ser barato, es ideal para aprender de física, especialmente sobre "la conservación de la energía".translate

to use it only as decoration. in my opinion you can only use it as decoration because it will stop directly its not perfectly made, and because its low quality and its beyond my expectation as the picture.translate

simple newton cradle. Pros: small, simple, working quite well, good for demonstration of physics principles. Cons: a bit cheap fabrication. Overall: satisfaction, good enough for what i needed.translate

i have always wanted one of these. very good to put in a glass display cabinet that is enclosed so nobody can touch it. if newton was alive, he would not able to prove his theory with this model. it does say mini but this is very small. should be described...translate
