Science Fair Not -Working vacuum
Hello, I am in the 7th grade do a science fair this year. I am making a vacuum cleaner, I used an average sized small plastic box, and a 12V computer fan. I also have a plastic tube that I shortened for the sake of making it not have to suck from so far away. My problem is, is that I cannot make it have enough power, I am positive it is getting 12 Volts of power from my 12V batter I got at ACE Hardware the other day. But it sucks little to nothing, I put it in backwards the way it sucks in. I am very stuck and it is due on Wednesday but I really need it done this weekend, help me please. Any thoughts or suggestions help!
