Product Information

You don't need a vacuum pump to demonstrate that sound does not travel in a vacuum.
Simply pour a very small amount of water into the flask, and heat using the flint glass burner. When the steam has escaped, and the flask is shaken, the jingle bells cannot be heard.
Some assembly required; instructions included.
