The Marble Whacker

STEM Contest 2018

I enjoy building and creating things and when I found out there was a contest, I thought it would be fun to give it a try.  My machine, the Marble Whacker, uses the domino effect to move the marble into the cup to make a splash.  First, the battery operated train pushes the baseball along the train track, which runs into the dominoes, making them topple over bumping into the stationary marble, which goes through the funnel leading through the switchback marble track construction, which ultimately sends it through a hole dropping down into a cup full of water to make a splash.
