This is what you want it to do…
The intent of the event is to have a falling mass propel a cart carrying an egg down a track as quickly as possible and end up with the egg as close to the terminal wall without…
as quickly as possible!!!

Building suggestionsFirst and foremost, build early, practice, log, and calibrate as many runs as possible.Use a plastic egg filled with any material to around 65 gAlways build just under/over the dimensions!!!! Make the transport as light as possible Perhaps try some different floor surfacesDid I say calibrate?Strongly consider using aligning devices since you need the transport to go as straight as possible
