I made a tickle machine from Little Bits. My goal was to get it working and tickle people.  To get it working I had to get a battery, a cord, a switch, an extender and the electric motor. I also needed a feather and some masking tape. I connected the battery to the cord that had the switch on it, then to the extender and last to the electric motor. I taped the feather to the electric motor shaft and tickled my classmates.
