What to do with a child on a snowless winter vacation? Invite him to make an electric machine. And time will pass faster, and the child will find out useful things. And how to make a machine from improvised materials we will take a look at the Master.
Tools and materials:
-Four plastic covers;
-Plastic bubble;
-Battery;
-Engine;
-Impeller;
-Insulating tape;
-Two wooden sticks;
-Plastic tube;
As you can see, the set is available. The engine can be taken from any children's electric toys. The impeller can be made from a plastic bottle. Instead of the battery, you can take finger batteries.
Step One (and Only): Build
The assembly is simple, therefore, we will not break it in steps.
Install the impeller on the engine. We wind the engine to the bubble, the impeller over its edge.
We attach the battery.
On the other (lower) part of the bubble, front and back, screw plastic tubes.
In traffic jams makes holes. Pulls the wooden axis into the guides. Installs traffic jams.
Connects one end of the battery to the motor contact. If desired, a circuit breaker can be added. Connects the second end of the battery to the second contact of the motor. The engine runs, the impeller spins, and the machine rides. If the engine is spinning in the wrong direction, just swap the contacts.
