1. Remove the fan belt from the car.
2. Place it in a elaborately decorated box with a false bottom and close the lid.
3. Distract your audience by talking about something in the vicinity and divert their attention to it. 4. Make sure you have put a fanbelt from another Corolla, preferably a 2000 or 2002 model in the false bottom before you have begun this 5. While your audience is distracted, turn the box upside down. 6 Say a group of nonsensical words to make it sound magical 7 pull out the new fan belt, and every one but you will think it has changed, which will be the nearest equivalent to it being actually changed. If the situation was the converse, ie, only you think it has changed, then you risk being placed in care.
