4M Green Science Potato Clock, Chemistry Engineering Lab

Very good , working perfectly

Not so well made. But for kids it’s perfect. For the price I would says it’s worthy.

Quite light but great for learning

This product is very affordable but also very effective to demonstrate the functionality to your kids. I had some issues on setting up clock time but its not really important, as the idea of making a battery and making clock tick is more important

Kind war sehr glücklich darüber...liebt Kartoffeln aber noch mehr als Flo Wirtz.

Un buen esperimento para hacer con los niños

I bought this product to teach my children in a fun way about digital time. We all had a fantastic time discovering the various fruits that can work the clock. Also, as the fruits have wilted, the children have been amazed by the drying up process and discolouration of the fruits. My only worry, and it is a big one, is that the instructions with the potato clock state that the electrodes can be placed in various liquids to make the clock work. I was a tad concerned that this would give my children the false impression that they could put any electrical worries in water to make a product work. Therefore, I removed the instructions and never mentioned anything about using fluids to power the product. All in all this is a fun product that gave lots of fun, investigation and learning. I am delighted I bought it!

très bon article pour faire découvrir la physique aux enfants et en avant pour un monde autrement avec des jouets intelligents

Prodotto molto simpatico e affascinante, per quanto vi possa stupire un orologio patata. Sicurmante fa parte di quegli esperimenti molto utili ai bambini per avvicinarsi al mondo della fisica/chimica in modo divertente. Sicurmante non è un soprammobile o un oggetto da tenere in modo stabile in un posto, ma lo consiglio vivamente.
