Great tutorial you have here. Will this apparatus be effective if I will use it for a physics experiment?I want to use this apparatus to make a vacuum chamber to demonstrate why sound cannot travel to vacuum.

Unfortunately this vacuum pump is not powerful enough to create absolute vacuum to demonstrate this effect. You need a more powerful/expensive device for that.
