جزاج الله خير اختي انا عندي برزنتيشن ابلتي انهبلت عليه عن الكولا اللي اخترعوها عن طريق الخطأ اللي تبي تقدر تغير و تكتب كولاالأول اخترع عن طريق الخطأInvented by mistakeThink of all the things we use in our everyday lives. Some of them are very practical, making our lives safer and easier. Others simply make our lives more fun. Now think of how these things got started. Have we always had them? Of course not ! someone had to invent them. Many inventions take years to develop. Other inventions are the result of pure luck. The amazing thing about these inventions is that they were invented by mistake !such as cola drinks ,chocolate chip ******* and ice-cream cones.The cola drink was invented in 1886 by a man who was mixing a remedy for his headache, he began cooking different ingredients in a big kettle. One of the things he added was a bunch of cola nuts. when he tasted it for the first time it was very good. later he added water to the mix and poured it over ice , it was even better that way ! and then one day by mistake he added bubbly soda water rather than plain water. and that was the first cola drink. He wanted something for his headache but he invented the most popular drink ever..
