How can I unclog a toilet without a plunger?

I believe some tissue is clogged in the toilet. For some reason, we never got around to getting a plunger in the house. I am a single mom and both my kids are asleep so i can't go out and get a plunger right now. The toilet bowl was full to the rim with water and I got an old bucket and emptied it out. How can I unclog the toilet? I have tried a wire hanger and that didn't help.
