A distinct difference in air pressure is actually what causes air to rush into the vacuum to replace the air that is being pulled through. Inside, there is a filter or a filter bag that keeps the dirt, a solid, in and lets the air pass through. As a science experiment, or to cleaner, you can assemble one from a few parts that are pretty easy to find.

Cut a hole in the side of the bottle. This is the exhaust hole of the vacuum cleaner. Dust needs to be kept in the bottle while the air goes out. Something as simple as a kitchen sponge will act as a filter.

Glue the sponge to the inside of the bottle over the hole. Step 4 - Finish Connections Take one end of the longer hose and use the silicone to attach it to the other hole in the pump, the one that sucks air in.
