The device must have a rigid backstop touching the egg, and the egg mount must not be padded. Once the device has been set in motion, it may not be touched or otherwise guided until it has come to a complete stop. The testing surface will be smooth and flat, and the device must stay within 3 meter-wide lane. The finish line will be 10m from the starting line. The front tip of your egg will be lined up behind the starting line.
Timing begins when the device comes to a complete stop.
You'll have a maximum of 10 minutes to set up your device at the starting line. After that, you will be disqualified. Your entire egg must cross the finish line to be eligible. You may hold your device and release your brick to start its motion, but no push or pull starts are permitted. Stopping mechanisms must work automatically.
