We recently had a Star Wars party for my son, who was turning 7.
We started off the party with coloring pages for the boys as they were arriving. We printed those from the internet. The first activity was in the driveway where I had drawn two "Death Stars" about 5 feet apart. The kids were divided into two teams. Each team was given a bucket of water balloons and had to erase the Death Star by bombing it with the balloons. The kids had so much fun with this! We made Light Sabers by cutting a pool noodle in half and covering one end in duct tape and used them for the following "Jedi Training Course". The boys had to first tap a balloon on the end of their light sabers 5 times and run to the next station where there was a Darth Vader made from a clothes hamper covered in posterboard and turned upsidedown. On the top of the hamper was an empty milk jug, weighted slightly with sand and covered in black posterboard. I printed a Darth Vader mask from the Star Wars website and attached it to the milk jug. The boys were given a bucket of balls and had to throw them to knock off Darth Vader's head. Then they ran to our swing set where they had to climb the rope ladder to rescue Princess Leah (large bear wearing a mask - also printed from the web - and a pillowcase), they slid down the slide and ran through a series of cones where they had to pop bubbles that were blown toward them with there light sabers. They crawled throgh a tunnel and met Darth Vader at the end of it. (I had an older child from the neighborhood dress up). They had to "battle" Darth Vader with their foam Light Sabers to get by. This obstacle course was a huge hit - they all wanted second turns. We were ready for a calmer game at that point, so we moved on to version of pin the tail. I had enlarged a picture of the Death Star and glued it to posterboard. We used an extra light saber and painted the end in orange tempera paint. The blindfolded kids were aimed toward the posterboard and had to "explode" the Death Star by touching the painted end to the poster. We also had a pinata. We played the Star Wars soundtrack throughout the party. We had cupcakes with Star Wars rings R2D2, C3P0 and Darth Vader. The rings can be ordered online or you might have luck getting them at your grocery store if you ask in the bakery - that's where ours came from. For favors, the kids got to keep their Light Sabers and the candy from the pinata as well as the rings from the cupcakes. I also found Star Wars fruit snacks and stickers. In addition I printed masks for each kid from www.starwars.com. There are 9 different ones to choose from and they were a huge hit!
