Vacuum pump with NO moving parts (Patreon)

Vacuum pump with NO moving parts

I demonstrate the importance of surface adsorption and use it to produce a clean, low cost type of vacuum pump. Note: If you ever notice the pressure meter go blank don't worry, there wasn't an issue. The meter automatically turns off to save power.
