2. H.J. Bulten NIKHEF annual meeting, 21-22 Dec. 04 Showers  Hisparc: outreach project  bring high-school students in contact with science  participate in scientific experiment  air showers: highest energies occur rarely (e.g. 1 event per 100 square kilometer per year)  determine energy and direction with scintillators on school roofs. (figure from Nagano en Watson, Rev. Mod. Phys. 72, 689 (2000)).
