Hello Ma'am/Sir, I'm a grade 10 student and I have troubles dealing with my group's research idea. We decided to make a water vacuum using recycled materials that looks like this https://www.youtube.com/watch?v=jkQsBD5WtDo
And because our idea is absorbing water instead of dust, we decided to put a hose in the side so that the water will exit there. Is our idea possible?

The exit point for the water must be behind the impeller (i.e on the high pressure side of the fan). Putting a hole in hole in the side of the bottle in front of the impeller (on the low pressure side) will draw air in through the hole, as opposed to pushing water out.
