Tomatoes (Tomato rungisia vulgaris) were thrown by an automatic tomatothrower (Wait & See, 1972) monitored by an all-purpose laboratory computer (DID/92/85/P/331) operated on-line. Repetitive throwing allowed up to 9 projections per sec, thus mimicking the physiological conditions encountered by Sopranoes and other Singers on stage (Tebaldi, 1953). Care was taken to avoid missed projections on upper and/or lower limbs, trunk & buttocks. Only tomatoes affecting faces and necks were taken into account.
Control experiments were made with other projectiles, as apple cores, cabbage runts, hats, roses, pumpkins, bullets, and ketchup (Heinz, 1952).
