Membuat senjata api (senpi) jenis pistol ternyata hanya perlu biaya Rp 200.000. Setidaknya ,begitulah pengalaman Miftah Yama Fauzan, siswa kelas 10 SMAN 1 Kabupaten Sidoarjo.
Remaja berusia 15 tahun tersebut berhasil membuat prototipe senpi elektronik. Tanpa suara letusan, pistol buatan Miftah mampu memecahkan kaca.
Temuan Miftah telah dipresentasikan di depan dewan juri yang berjumlah 12 orang enam di antaranya bergelar professor dalam Lomba Penelitian Ilmiah Remaja (LPIR) Tahun 2009. Kegiatan ini digelar Departemen Pendidikan Nasional (Depdiknas) di Jakarta, Agustus 2009 lalu.
