Not only can lighting LEDs, potatoes can be made into a self-driving car running at 7.3m / day.

The experiment to generate electricity from potatoes to light a small bulb is no longer strange to many people, but making a self-driving potato like a self-propelled car is amazing.

1. Homemade ultra-light light switch, only you can turn it on
2. Unbelievably true, paper blades cut plastic and wood

The world's first potato self-propelled vehicle was created by engineer Marek Baczynski. By adding solar panels to the potato, Marek was able to upgrade the potato potato into a car that could run a distance of 7.62cm at 7.3m / day in just 25 minutes.

Not only can he turn around, this unique potato car is also equipped with Marek's ability to find out where to have the light to park (charge) or follow him throughout the room.
