The options for an outer space party are, much like outer space itself, endless! Paste glow-in-the-dark stars around a dark room, or have fun with planets on all of the surfaces! You can invite some Martians or pass out space helmets for a little extra excitement. Shiny clothes and stars are a must, and a few glowsticks inside of balloons can go a long way in transporting your party to the surface of Mars. There is also no better invitation than a rocket ship inviting your kids’ to travel light-years away to celebrate your own astronaut making another trip around the sun!
