Today, in honor of Isaac Asimov’s birthday, is National Science Fiction Day—the day for all techies, Trekkies and bookworms to celebrate. In honor of the day, here are 10 things to do.

10. Read a Sci-Fi Novel

My latest favorites were The Hunger Games; what were the best science fiction books you’ve recently read? Check out a list of best science fiction books of 2010 if you don’t have any ideas.

9. Have a Sci-Fi Marathon

Watch a marathon of your favorite science fiction movies, or read your favorite book series. Look up science fiction series fanfiction or short stories on the web.

8. Speak in Your Favorite Sci-Fi Language

I have to confess that I don’t know any science fiction languages, but if I had to learn one it would have to be Elvish (which isn’t so much sci-fi as it is fantasy, but that’s more of my cup of tea). I’ve heard of many fans who are able to speak made-up languages, though, and it sounds like a lot of fun.

7. Make a Weapon

Invent your own, or make a model of your favorite from a movie, book, or TV show.

6. Make a Meal

Shape a cake as an alien, design your own Futurama Slurm, or something scrumdillyumptious from Willy Wonka and the Chocolate Factory.

5. Introduce Your Child to Sci-Fi

The Magic School Bus is a wonderful way to do this for young children. Some great books for older children include Animorphs, The Guardians, Dinotopia, and Ender’s Game.

4. Make a Robot with Your Child

Or make a rocket, or slime, or whatever he or she is interested in.

3. Write Your Own Sci-Fi

Write and direct a mini movie starring your friends or family. Write a short story, poem, or start a novel.

2. Make a Time Capsule

Bury it or store it somewhere and don’t open it for ten years. Be sure to include a list of predictions that you think might happen by 2021 and see if they come true.

1. Dress Up as Your Favorite Character

Maybe it’s Princess Leia, or Mr. Spock, or The Terminator. Perhaps you’re into aliens or cyborgs or hybrid creatures. Frankenstein’s monster is pretty much the icon of science fiction (why isn’t Mary Shelley’s birthday the inspiration behind National Science Fiction Day instead?), and X-Files fans would probably enjoy dressing up as Mulder or Scully.
