A spinning pummkin surprise waiting to spook trick or treaters on Halloween night!
A motor and switch or other activation method will be required to surprise trick or treaters when they approach.
A small 6V geared motor that spins from 50 to 80 rpm is recommended, powered off of two AA batteries connected in parallel.
Assembly: Insert the motor with gearbox into the base (blue stand in picture), then connect the gear to the shaft with a press-fit. After that, take the large pin with a round bottom (pink in the image) and push it through the crown gear, making sure that the hexagonal shaft area sticks out of the side with the teeth. Next, place the two smaller pins into the crown gear and connect to pumpkin to those pins. Then, place the lid of the pumpkin on top of the base of the pumpkin and push the stem through the lid into the base of the pumpkin. You're done!
