Speaking of whacka, I think everyone is familiar with it. Hit the hamster is a very interesting game. The rules of the game are simple. Knocking down all the hamsters that appeared was successful. Because of its simple operation and high playability, it is deeply loved by children. Today, Science Dad shared an interesting science video to teach you how to make a simple whack-a-mole game machine with simple materials. How to make it? Let's take a look ~
Materials: cardboard, bearing, PVC pipe, plastic button, reduction motor, battery pack, switch.
Tools: hot melt glue gun, meat cleaver, mini cutter.
1. Make 1 base and 1 cover with cardboard.
2. Make a food stall.
3. Fix the bearing in the center of the base.
4. Fix the big gear on the bearing, and fix the small gear on the rotating shaft of the reducing motor. The big gear and the small gear are riveted together.
5. Fix three wedge-shaped paper strips on the big gear in an arc shape.
6. Power cord.
7. Make 8 small holes in the panel.
8. Sleeve the pipes made of plastic pipes on the corresponding holes on the panel.

10. Turn on the power and start the game.
safety measure
Be sure to pay attention to the safety of operation when using tools. The video only shows ideas and principles, and shapes, materials and tools can be replaced accordingly. The production process of science and technology needs to be accompanied by adults all the time, and children should not be allowed to operate alone to ensure safety.
Disclaimer: Scientific production involves certain operational risks. Parents should accompany their children to pay close attention to this safety precaution. Any safety accident in the production process has nothing to do with the magic experiment.
