There are many different ways to make a few extra hundred dollars, and I'm not considering a few of these ways..  One of the easiest for girls, is to sell your hair!  I was reading a story about a woman who needed cash fast, so that she could catch up on her late mortgage.  And she go $1,300 for 27 inches of her hair!  There are a lot of reliable websites online that will gladly take your hair for a lot of money.  Unprocessed hair is worth more, and the longer, the better. 
   If you live near a university, you could be eligible for a medical experiment.  Some are more strenuous than others, but there are more people out there who are becoming professional guinea pigs.  You can get paid between $50-$5,000 for one treatment. 
   Another is to sell your old jewelry that you never wear.  We've probably all seen the commercials, but it's actually a legitimate way of getting some extra cash.  You could have hundreds of dollars sitting in your box of jewelery that you never wear!

I dont think the whole using your body as an experiment thing is a good idea though. No amount of money is worth risking your health.

Many universities just use the undergraduates as their lab rats.  And they only pay them the most minimal amount of money, because they're younger and they don't have that entitlement yet.  But some of the tests they do can be harmful, you're right.  I'm sure there are some people out there who are willing to take the risks, living form experiment to experiment to pay the bills. It's their choice however, and it could turn out to be a good thing regarding scientific purposes and discoveries.

I'm sure it has some good benefits, but I agree with Mrs. Ugly,  no amount of money is worth losing your health. Imagine if that experiment makes you really really sick. Life threatening sick, what amount of money would you pay to make your self healthy again?
People could sell blood? Or sperm too.

My Biology teacher did this while he was in college.  For a while, people would ask him if he was on drugs because he'd constantly have scabs on the inside of his elbows lol.  But it's a good way to make extra cash if you think about it.  You can also give plasma too. 

I wouldn't trust any online things. My cousin did an online thing that was supposed to give her money. Basically they had her download pictures of houses, rooms hotels, things that had to do with interior decorating and all she had to do was put tips on how to decorate it. What types of things to buy where to put it. She would put atleast 50 tips on each room and get paid $100 on each one, and you dont even need a license or anything. Well She gave them her credit card number so that they could transfer the funds and instead they emptied out her whole bank account! She had about $5,000 in it and it all got stolen.

This is why I'm scared to buy things online. Unless it's sites from companies that I know of. Like shopping stores and stuff like that. I even get scared to use my credit card on sites like e-bay.
