The Lemonade + Explosion Machine

STEM Contest 2018

I am submitting this video for my son Joshua.   He is in the 1st grade and 6 years old.  He wanted to make a Rube Goldberg machine that would make lemonade and cause a splash...or more precisely, an explosion!  So, he invented this!  First, he pours the water into the machine.  Next, the water goes down the machine, and into the cup.  Finally, he stirs in the lemonade mix and enjoys his drink.  For the explosive reaction, he pours in vinegar, and the vinegar goes down the machine and lands in a bowl of baking soda to make an explosion!  Enjoy!  Thanks for watching!
