Water Balloon Launch Challenge

Combining physics and fun!

The Water Balloon Launch Challenge was a perfect tie-in with Dock's Homecoming 2018 emphasis on STEM (Science, Technology, Engineering, and Math).

Four teams of students competed to design a trebuchet that would propel a water balloon for both distance and accuracy. All four trebuchets worked well—congratulations to the student engineers who designed and built them!
