- and something to keep the cardboard circles from falling out (i used k'nex pieces)
Step 2: Gluing the motor to the cardboard
Take the cardboard and put the glue all over it then put the motor in it with the "on switch" facing up. (You can also tape the motor to the cardboard.)
Then put the k'nex stick through the cardboard and the hole in the motor, then put the skewer on through the front.
