2. Drop a mass from a given height and get it as close to the ground without touching

3. Elastic Cord More than one material More than one strand Attached closed metal ring ½ - 1 inch diameter Will not open Must meet elasticity test

4. While suspended vertically Bottom meter of the cord Stretch to at least 1.25 meters with 500 gram mass attached Return to original length (approximately)

5. 50 – 300 grams Regional – 25 gram multiples State – 10 gram multiples National – 1 gram multiples

6. Regional and State 2 – 5 meters Same or different heights National 5 – 10 meters Different heights

7. Multiple spotters Digital video cameras Touch or no touch Carbon paper Fine powder

8. Elastic cords impounded before posting of mass and height(s) No physical alterations to elastic cord (except for marking drop locations) after impound

9. 2 drops Same mass each time Height Regional – same or different National - different

10. 5 minutes to prepare device in holding area 5 minutes to complete both drops

11. Sum of distance between surface plane and lowest point of device Teams with one touch will be ranked below teams with no touches Teams that fail elasticity test will be ranked below passing teams

12. 1 ST – Single best overall drop Closest to landing surface Either drop 2 nd – Cord with greatest stretch in elasticity test

13. No appeals after device has left impound area
