Measure launch velocity for truly quantitative projectile motion labs The Mini Projectile Launcher & BeeSpi Bundle elevates a classic lab by adding the one thing students need most—real velocity data—turning projectile motion into a rigorous, confidence-building investigation. This compact system pairs Arbor Scientific’s accurate Mini Projectile Launcher with the BeeSpi V meter, giving students direct access to launch velocity—a key variable that’s often calculated rather than measured. Designed for indoor physics labs, the launcher projects 16 mm steel balls over controlled ranges ideal for benchtop or bench-to-floor experiments, while BeeSpi adds real data to strengthen prediction and analysis. With three repeatable launch speeds, adjustable launch angles from 90° to –45°, and an exclusive magnetic metal cup for improved consistency, this bundle turns classic projectile labs into fully quantitative investigations students can trust. Why Teachers Love the Mini Launcher & BeeSpi Bundle Quantitative projectile motion: BeeSpi measures launch velocity directly, eliminating guesswork and assumptions. Precise and repeatable launches: Three spring tensions deliver consistent speeds with no measurable spring fatigue. Exclusive accuracy upgrade: Magnetic metal cup keeps the ball perfectly seated for reliable results. Smooth, controlled launches: Cable release minimizes disturbance; clamp-ready or free-standing use.
