Sometimes the greatest things are invented by mistake. The greatest mistake of all time could be those delicious snacks in your corner drugstore.

One day ,a woman was making chocolate cookies. When she ran out of chocolate powder(粉)， she took out a chocolate bar and broke it into little pieces. She added the pieces to her cookie dough(面团) and baked (烘烤) it. She thought that the chocolate would (1) melt in the oven and make chocolate cookies. Far from melting, the pieces of chocolate stayed hard. When she took them out of the oven ,she had chocolate chip cookies.

Another accidental invention was made by Frank Epperson, an eleven-year-old boy .In 1905, Frank sat outside on a winter evening ,mixing up a big jug (罐) of powdered soda pop. Frank accidentally left the jug out during the night . When he went outside the next morning ,he found the mixsure in the jug frozen(冻僵) with the mixing stick stuck in the middle. Frank pulled out the frozen pop and tasted it . It was delicious ! Frank started selling Epperson Icicles for 5 cents each. He later changed the named to (2) Popsicles.
