Changes we made on the second prototype:

Made the rubber bands attach to pad, Made there be indirect action with wheels controlling string on both sides of the blocker which can pull it both ways, Used metal as the secondary blocker. Cleaned up glue from last time, used two more rubber bands, Made the primary blocker stronger,

Changes we need, Change all materials out of cardboard to wood or other, Make the blocker even stronger, Make movement system better and faster, HAve fun and be safe
