Salt Water Fuel Cell Engine Car DIY STEM Build Your Own Kit

An interesting car kit for a child or any one who still has a child in them and a mechanical aptitude. Good quality and well defined step by step instructions provided for an interesting building experience. It works absolutely fine with five drops of salt water!

D'après les commentaires, je ne pensais pas être déçu. Et je confirme. Cette petite merveille a ravie mon petit. On l'a monté à 2. Ca permet de comprendre les bases de la mécanique et le coté pilte à combustible totalement écolo rend la chose splendide. Vraiment recommandé.

I purchased this salt water vehicle as i was looking for something different for my 7 year old nephew. Hes loves Lego and generally building anything. This was a perfect present for him, we spent hours in building it together and he enjoyed every moment. Months down the line he still very much enjoys playing with it unlike most other toys which simply once played are put in the cupboard. The salt watery was at time hit and a miss but worked for most part. its a excellent educational toy with lots of fun building it. the delivery was very quick, build quality of the item is very good and would highly recommend it.

Works well. Also produces good torque. Runs for about an hour in one shot of salt water. Only worry is the sheets not lasting for long time.
