[Engineering] Building a mini wind-powered car

Due to a persistent cough from the serious haze, Jae (7y10m) has been staying home the whole week. He received a Science kit for his last birthday and we finally got to fix it today.

It’s a simple and interesting kit where he explored questions like:

• Why does the car slow down when turning?
• Why does it reverse when we swop the wires for the battery compartment?
• Didi meddled with the wires! Why are the blades turning but the car is not moving? (Answer below)
• Is it going to fly?

Since he has thrown the box away some time back, I don’t have the product details, so you may try searching for “diy motor car kit” at major online stores.

You may check out the examples at Amazon here:

• 5 Set STEM Kit*

• 6 Set DC Motor Kit*

Happy building and learning!
