"A pair of Vietnamese high school students from the south-central province of Binh Dinh have developed a bookshelf able to float. The model, recently awarded the grand prize at the provincial inventors contest for students, was created by 11th graders Le Quang Hoan and Le Thi Bich Quyen in Tuy Phuoc District... The idea of a floating shelf came to the pair when they were the 10th graders at High School No. 3 Tuy Phuoc. Quyen recalled a deluge that swept through her house and completely submerged the wooden shelf containing her coursebooks and materials."
