I am working on a way to solve the problem, and was wondering if anyone knew of any materials that could assist me. I have found Kevlar to not be sufficient enough to stop a high caliber bullet.

I always heard this was a myth. But today i came across a report on www.preventcancer.com (ran by the cancer prevention coalition) that said that it does increase the risk. It also said this was particularly the case in women who started the pill in their teens or early 20s without having a full term pregnancy first. so what's the truth?

I am in chemistry, and we've been learning about mass, volume, and density. I have a few jems that I need to weigh in either grams or carats, and I was wandering how I could find the mass of these objects without using a triple beam balance. i would like to be able to use a normal house-hold appliance.

We have had some time to figure this out, but the closest we are to flying is going on a airplane. We basicly have primitive flying technology, but is anybody really working on reversing our gravity againts itself so we can fly?
