How can I break a bike chain?

I just bought a new SRAM single speed chain from the local Trek store for my haro that I just finished restoring. I was able to break the original chain by pulling off the c-clip with a scratch awl, but the chain shattered after riding, so I had to replace it. Now this one is too long, and my scratch awl trick doesn't work, and I can't pull my axle back on my dropouts. My dremel is broken, so I can't grind down the pin, and the store is closed until noon tommorrow, but I need the bike before then. Is there any trick for breaking it?
