Demonstrating Propulsion Using Water Balloons!

Go to the website link: https://www.osc.org/demonstrate-laminar-flow-at-home/  and complete the lab (you will need water balloons and a space that you are ok with getting wet). This lab discusses how differently size openings in a water balloon allow water to escape at differing rates. After completing the lab, explore your findings. What size opening allowed the water to exit the fastest or travel the furthest (say piercing the balloon with a pin vs a knife)? Try to quantify your results in a table, noting the size of each opening and how far the water travelled. What do you notice? Finally, try to relate your findings to a rocket. What does this lab say about the ideal size opening that a rocket nozzle should have, if anything?
