Everyone wants to get the most bang for their buck; it doesn't matter how much money they make. Whether you are looking for an activity for yourself, your family, or your friends, there are plenty of pastimes for you to take part in.

The best part is that you don't have to spend a fortune either. In fact, all you really need is $20, and it can indeed go a long way. Here are some ideas for fun things to do under $20.

Museums and Planetariums

Sometimes, museums and planetariums can be expensive, but sometimes they aren't. In fact there are usually specific days of the week where you might even luck upon free admission, if not a seriously discounted price. You may have to go to the museum website to find out which days are free or discounted, but it's well worth a look, especially if you like learning about planets or science in general. This one is also a good one for the kids, if you're looking to engage them in something particularly mentally stimulating.

Discount Theaters

Who says you can't go to the movies for $20 or less? We all know about the megaplex theaters, equipped with all the bells and whistles that we are all accustomed to and love, but if you check your local Yelp or Yellow Pages you'll find that there are cheaper theaters as well. For example, discounted theaters might offer tickets for as little as $3-$5. Although the theaters that offer cheap tickets usually show movies that have already run at the bigger theaters, they are still a great option. The best part is that with a price as low as $3, you can take in several movies in one night, providing that you skip the snacks.

Farmer's Markets

Yet another option for the kids in your life, or perhaps the entire family, is the farmer's market. One of the best parts about farmer's markets, aside from the free admission, is the samples. You get to sample all different kinds of tasty, homemade products and there is no commitment to buy anything unless you want to. Depending on what day you attend there may even be activities lined up for children and/or adults to participate in, making for an all-around amusing time.

Walking Tours

No list of fun things to do under $20 is complete without mentioning being a tourist in your hometown. It's a surefire way to re-discover (or discover for the first time) everything that makes your hometown the unique place that it is. Sightseeing won't cost you a thing, but you also can sample some of the fantastic food trucks that will undoubtedly give you a taste of the hometown cuisine, all within your budget. Or, you could even bring your own food and have a picnic in a local park, to further enjoy the sights.

Having fun doesn't have to break the bank. Whether you're looking to spend less money or you're looking for ways to stretch what money you do have, there are ways to find some enjoyment without spending a whole lot. Going to the museum, discount theaters, farmer's markets, and walking tours are all fun things to do under $20.
