Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Parts
you will need:
A small DC motor
Any kind of Fan blade, in this case i used a laptop heat sink fan
A cardboard tube
2 sheets of A4 paper or card
Step 2: Make Your Internal Fan
Simply attach your blade to your motor using hot glue
Step 3: Cutting
make two large circles by rolling the paper, and then they must be able to fit one inside the other, then trim them to size, ensure that they are both longer that the diameter of your tube
next, cut a hole in your larger tube that is the size of cardboard tube
Step 4: Fit the Tube
splay one end of your cardboard tube, then fit through the hole and secure it, ensure that it is not covered in any way
Step 5: Insert the Fan and Secure It to the Base
I used cocktail sticks that were glues to the fan, and then attached them to the base on the cardboard tube, i then attached the whole rig onto my breadboard, because it was the only thing i could find that would work, and it made it easy to connect to my power supply, feel free to use your inntiative for this step.
Step 6: Connect to the Power
Connect it to your power supply, either battery or USB cable and feel free to add a switch or something, to activate and deactivate it, thanks for viewing my instructable, have fun.
