  • ESSENTIAL FOR SCIENCE EDUCATION: This Vacuum Bell Jar is an ideal teaching aid for science education, designed for classroom labs to visualize the changes in sound under vacuum and help students understand the principles of sound propagation
  • More Experiments: A cup of boiling hot water has been discharged into the bell jar, and then pumped, you can see that the hot water in the cup is boiling again. In addition, this instrument can also be used for experiments such as vacuum fountain, evaporation icing, vacuum coating, and atmospheric pressure.
  • MULTIFUNCTIONAL EXPERIMENTAL TOOL: The Sound Physics Demonstration Cover can not only be used for sound propagation experiments, but also demonstrates the re-boiling of water under vacuum, vacuum fountains, evaporation and icing, vacuum coatings, and atmospheric pressure, which is a multi-functional tool that enhances the teaching and learning fun
  • SIMPLE AND EASY TO OPERATE: The vacuum demonstration hood is easy and convenient to operate, students can operate by themselves, through the vacuuming process to observe the phenomenon of sound gradually diminishing until it disappears, as well as closing the exhaust valve after the ringing continues but no sound, to deepen understanding
