To increase the probability that the expert's tests, experiments, demonstrations and models will be admissible for the courtroom, the expert should follow these steps:

• Be thoroughly familiar with the facts of the case.
• Have accurate measurements available.
• Be familiar with the progression of events that occurred.
• Use the same materials that were involved in the events.
• Meticulously track tests or experimental steps.
• Record the tests or experimental events carefully.
• Make demonstrations similar to the actual events that occurred.
• Make models to precise scale.
• Detail all findings, both positive and negative.
• Do sufficient research to establish that the test or experimental procedure is scientifically and technically recognized as authoritative.
• Consult with counsel to ensure the best presentation for admissibility.
