Egg drop vehicle

The objective of this event is to prepare an egg re-entry vehicle that will safely return an uncooked egg to the ground. The vehicle must be built from approved materials and should be designed to safely carry an egg to the ground from the fourth floor window of Allderdice High School.

B. Apparatus

• Materials:
  
  • Any parts from the parts kit.
  • Rule update #1 Any parts from parts kit EXCEPT plastic bag. No parachutes (that would be "silly")
  • No chemical alteration is allowed.
• Dimensions:
  1. Size: The egg re-entry vehicle must fit within a 20 x 20 x 45 cm unrestrained initial volume prior to dropping.
  2. Weight: There is no weight restriction.

C. The Competition

1. Egg re-entry vehicles must be submitted for inspection 1/2 hour before competition.
   
2. For each team's vehicle, 1 Grade A medium chicken egg will be supplied.
   
3. The drop will be conducted as follows:
   
   • The drops will be made by putting the vehicle into a box with a retractable bottom floor. One team member may load the vehicle into the box, then a judge will release the vehicle by retracting the floor.
   • The vehicles will be dropped from the same initial height, the second floor window in the back of the school, one at a time.
   • The vehicle will be opened and the egg immediately inspected.
   • Each successful drop will be followed by a drop from the next higher floor of the building. A successful drop from the fourth floor will be followed by another drop from the fourth floor with the same egg. If the egg survives three drops from the fourth floor, testing will cease.
   • Any distribution of the package and its contents over the landing area or on spectators must be cleaned up by the dropping team.
     

1. The egg re-entry vehicle which preserves the egg longest will be declared the winner.
2. In the event of a tie, (i.e. both eggs break when dropped from the third floor, both survive three drops from the fourth floor, etc.) the least massive vehicle will be declared the winner.
