Marble loop roller coaster launcher!

  1. Dec 13, 2011 #1
    Help me here.

    I need to figure out how to launch a marble so it navigates a vertical loop, then follows projectile motion at the end of the loop

    The design must use elastic potential energy to do this and must consistantly launch it consistantly to a specifyied location.

    I can't figure out how to launch the marble..

    Any ideas other than a compression spring??

    Seems like you have a choice between spring and elastic band.
