The hypothesis is that a magnetic chain reaction can be used to launch a steel marble at a target with high speed.

You will tape four magnets to a wooden ruler, place nine steel balls to the right of each magnet, and set a steel ball in the groove to the left of the leftmost magnet.

You will need a wooden ruler, Scotch brand transparent tape, four magnets, nine steel balls, and a sharp knife.

This project demonstrates the power of magnetism and kinetic energy. When the first ball is released, it is attracted to the first magnet and transfers its kinetic energy to the other balls, causing them to speed up and hit the target with considerable force.

This science project is unique because it uses a simple chain reaction to launch a steel marble at a target with incredible speed.

Experiment variations to consider include changing the distance between the magnets and using different types of magnets.
