Thailand / Udon Thani / 2015 / HIV prevention / Steyler missionaries teach pupils what HIV and AIDS is and how to prevent it. An experiment shows how easy it is to get infected. Everyone--52 pupils--getting a glas with water and a syringe. In one of the glasses is not only water, but also colorless baking powder--vicarious for HIV. Now they have to change partners three times, each time with the syringe they exchange liquids--vicarious for exchanging body fluids during sexual acts. After that another liquid is dripped into to their glasses. This liquid colors the ones which contain baking powder. 24 of 52 pupils got the baking powder in their glass-- 24 got „infected“. © Sandra Weller / Anzenberger
