Penny stocks.
 

Is this a reasonable thing to put like $100 into if I am bored? What are good sites and resources for these things? Can anyone give me some advice on them?

The only advice I can offer: "Investing" in penny stocks is actually speculating.

Think of this $100 as you would in Vegas.

Penny stocks are great if you have no expectations of getting your money back. If you're ok with the idea that you might make some money or you might lose it all, it can be fun, but if you're expecting that $100 to come back to you, you'll most likely be disapointed.

I stopped playing penny stocks about 15 years ago when I decided I wanted to make money, not lose it. Your results may vary.
