In a press release, Guinness World Records said that the lesson was registered under the "biggest mass chemistry lesson to be conducted simultaneously in different places." The experiment took place under the initiative of the Science and Technology Ministry.
This makes it the only ministry in Israel (and maybe the world) to hold a world record. The participating institutions will receive certificates to confirm the record.
The experiment, which was first demonstrated to Ilan Ramon in 2003 by a group of high school students from the ORT Kiryat Motzkin High School, involved testing the chemical reaction in “growing” crystals in a solution under conditions of gravity. It was completed six hours after the shuttle’s takeoff.
The previous record was held by Belgium where 562 people carried out an experiment in Brussels.
Ministry director Menachem Greenblum says the Guinness acknowledgment "brings additional global honor to Israel as a scientific powerhouse."
Israeli scientist Dan Shechtman won this year's Nobel Prize in chemistry.
