Experiment with charged particles in a "pinball game" to predict the path of moving charged particles with/without the influence of a magnetic field. If you win, you'll be treated to movie that explains how this concept helps IBEX make measurements.
Knock down pins with a proton ball in a magnetized lane: position the electrical wires to create the correct magnetic fields to keep the proton in the lane. Nail all the pins and move on to the next lane.
