The Science
CHANGE THE VARIABLES. CHANGE THE RESULT.
π§
Water Level
The biggest factor. More water = more mass to push. Find the sweet spot.
IMPACT
π¨
Air Pressure
More PSI = more thrust. But there's a limit β find out where that ceiling is.
IMPACT
ποΈ
Nose Cone
Pointed cuts through air better. Rounded is stable. Blunt β you'll see.
IMPACT
π¦
Fin Config
3 fins vs 4. Too small and it wobbles. Too big and drag slows it down.

About
BUILT BY A STUDENT. FOR STUDENTS.
Launch Labs started as a simple idea: what if learning physics felt like actually doing something awesome? Not reading about Newton's 3rd Law β but feeling it blast a rocket 100 feet into the sky.
Every kit is designed so students can change real variables and see real results. Water level, pressure, nose cone, fins β each one teaches something different. The website tracks your height. The lab sheet records your data. The science is built in.

Science Explainer
WHY DOES YOUR ROCKET FLY?
Three big physics ideas explain everything β from the moment you pump to the moment it lands.
Core Concepts
THE PHYSICS BEHIND THE FLIGHT
CONCEPT 01
Newton's 3rd Law
Every action has an equal and opposite reaction. Water shoots down β rocket goes up. The harder you push water out, the harder the rocket pushes back.
Action = βReaction
CONCEPT 02
Stability
A rocket is stable when the Center of Gravity (CG) is above the Center of Pressure (CP). Fins push the tail down when it wobbles, keeping the nose up.
Stable if: CG above CP
CONCEPT 03
Projectile Motion
Once the water runs out, your rocket is a projectile. Gravity pulls it down while momentum carries it up. Peak height depends on how fast it launched.
h = vΒ² Γ· (2g)
THRUST PHASE
Action & Reaction
Water ejects down β rocket shoots up. Thrust lasts a fraction of a second.
WATER
PRESSURE
20 PSI
The Two Big Variables
Water = propellant mass. Pressure = stored energy. Together they decide how high.
Variable Breakdown
WHAT EACH VARIABLE DOES
π§ Water Level
PROPELLANT MASS
Too little = weak thrust. Too much = too heavy to accelerate. Sweet spot is 30β40% full.
95%
π¨ Air Pressure
STORED ENERGY
Higher PSI = more force pushing water out = more thrust. Most rockets peak at 60β80 PSI.
85%
ποΈ Nose Cone
AERODYNAMIC DRAG
A pointed nose cuts through air more efficiently. At higher pressures the pointed cone gains you extra feet.
55%
π¦ Fin Config
STABILITY & DRAG
3 fins = less drag, slightly less stable. 4 fins = more stable, slightly more drag. Bigger fins help at low pressures.

Key Vocabulary
WORDS TO KNOW
Tap each card to see the definition.
Thrust
noun Β· physics
The force propelling the rocket upward, produced by expelling water downward at high speed.
TAP TO REVEAL
Drag
noun Β· aerodynamics
Air resistance acting opposite to the rocket's direction. Reduced by streamlined nose cones.
TAP TO REVEAL
CG
Center of Gravity Β· mechanics
Where the rocket's weight balances. Must be above the Center of Pressure for stable flight.
TAP TO REVEAL
CP
Center of Pressure Β· aerodynamics
Where aerodynamic forces act on the rocket. Fins push this toward the tail.
TAP TO REVEAL
Trajectory
noun Β· physics
The curved path a rocket follows through the air, shaped by thrust, gravity, and drag.
TAP TO REVEAL
Apogee
noun Β· rocketry
The highest point of flight β the exact moment you tap the Height Tracker button.

THINK IT THROUGH.
Answer these after your launches. Think like a scientist.
Q01
Which variable had the biggest effect on height? How do you know?
Hint: Compare rows where only one variable changed.
Q02
Was your hypothesis correct? What surprised you?
Hint: Compare what you predicted vs. what happened.
Q03
If you had one more launch, what would you change and why?
Hint: What combination haven't you tried yet?
Q04
Newton's 3rd Law: every action has an equal and opposite reaction. Where did you see this?
Hint: Think about what went down when the rocket went up.
Q05
How did the nose cone shape affect the flight?
Hint: How might shape affect air resistance?
Q06
What's your ideal setup to go as high as possible?
Hint: Use your data β what combo gave the best result?
Height Tracker
MEASURE YOUR LAUNCH.
Hold your phone like you're taking a photo. Line the crosshair up with the rocket. Tap the screen when it hits the peak.
How far are you from the launch pad?
1
Enter how far you are from the launch pad above.
2
Hold your phone upright like taking a photo β camera pointing at the sky.
3
Aim the crosshair at the rocket. The angle updates live as you tilt.
4
Tap anywhere on screen the moment the rocket reaches its peak. Done.
