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.
A major solar 'superstorm' such as the one in 1859 could cost $30 billion a day to the US electrical power grid, and up to $70 billion to the satellite industry.
