Physics project - need help!
I am building a physics machine that is supposed to use a hairdryer (Not sure what the Newton force of the hairdryer is) but it lifts 1 kg a certain distance in a certain length of time. You can do it in portions, like .5 kg once and then another .5 again. So far, ours is lifting nothing. We have it set up so that the hairdryer blows into cups, which are attached to a wheel. The axle rolls up string, which are connected to a series of four pulleys. The axle will turn as long as there is slack, but when hte slack runs out, it comes to a stop. Me and my physics partner have worked on it all day and we're becoming angry and violent. Do any of you have a suggestion? is there another simple machine we need to employ? Like I said before, all we can use for power is the uber physics hairdryer of pwn, which isn't very powerful. Project is due on Wednesday. Here is a crude drawing of it:

Any help would be appreciated. Thank you for taking the time!
