The structure and programme of the well constructed in P2 will remain unchanged.
3 Touch sensors are placed on the reel.
Each of the three sensors switches the reel on at a different speed and rotates it as long as it is held down (e.g. the motor speed changes between 30, 60 and 90)
The 3 Touch sensors remain on the reel, but the speed they set is picked from a range using a random number generator (p.: between 20-40, 50-70 and 80-100 speeds).
The rotation is stopped by an infrared sensor built into the reel when the old woman is placed in front of it.
