Tube Spike

STEM Contest 2018

Tube Spike is the name of my Rube Goldberg machine.  My name is Aaron, I am in 2nd grade.  I love building things more than watching TV.  After school, I like to build cars or buildings out of legos, and cardboard.  This was my first time building a Rube Goldberg machine.  The machine makes a splash by using spikes (needles) to pop the balloon that has water in it.  The hardest part was setting up the dominoes, since they would fall down often.  I had a lot of fails, over 20 I think, but it was worth it because SPLASH, it worked!  It was the best part of trying this project.
