4M Lemon Clock

Alles bestens.Danke.

Cheap but great fun to do with kids mine are 8 & 6it only took a few minutes to make but they really enjoyed doing it simple enough to not cause arguments and easy enough they can do it alone with very little help,They were very excited about what they created and both took it to school and there class were amazed and teachers alsoCan't imagine it will last very long but for a cheap bit of fun its worth doing

C'est amusant 5 minutes et puis... Terminé ! Rapidement l'horloge se dérègle. Difficile ensuite pour un enfant de 5 ans de la faire fonctionner de nouveau...Fan absolue des produits 4M, je suis ultra déçue par cette horloge ! En résumé : sans intérêt

Genial, algo tan simple y funciona!!. A mi hijo le encanta experimentar. Y claro, va "sin pilas" . lo que se gasta en vez de una batería es la oxidación de las barillas que reaccionan con el acido del limón.

Children love this experiment!Used this for our science lab, great way to show how the electricity flows through the lemon to the clock .
