Use your angle measurement and distance to calculate how high your rocket flew using trigonometry.

Learn how to build your own inclinometer and use it to measure the angle of your rocket's flight.

Build a water bottle rocket — tune water, pressure, nose cone, and fins. Check its stability, then launch for max altitude or to hit a target!

Label the water bottle rocket — drag the part names onto the nose cone, transition cone, body, fins, and more. Check your work!
