| Abstract: | A set of instability device was explored based on aluminum Pop-top was used as test sample. The vacuum pump was adopted to pump air into vacuum state, which produce negative pressure and form external pressure vessel. In this facility, the instability process and pressure were observed. The experimental design and the whole experimental process were accomplished by students independently, which plays an important role in stimulating the initiative of students. It could also cultivate the students＇ability of inquiry study and innovation. |
