Here is my take on the ninja birthday theme. I found so many great ideas on Pinterest. I was also inspired by the Clumbsy Ninja App. My boys love that game.
The ninja eyes were our placemats. I printed out one set of eyes and cut the eyes off the black. I didn't want to waste all my printer ink on the black part. Once cut, I copied just the eyes and pasted them to black card stock paper. Then I laminated them. I used the number 6 as a game. We spread them out throughout the party and had the ninja's hunt them down. The ninja with the most 6's won a special prize.
I used foam pipe insulators, red rope and red duck tape to make the nom-chucks. These were used the most of all ninja weapons. I copied an image from the internet to create the ninja stars. I printed out 3 on card stock and glued them together. It gave them more weight and durability when being thrown.
These are the ninja potions. The concept was inspired by the clumsy ninja app. This was the biggest hit of the party. If you are having a ninja party- definitely do this. We had a freeze potion, punching and spinning. The kids stayed hydrated, acted out funny impressions after drinking and they served as great transitions to each activity I used gatorade, 10oz water bottles and created fun tags with symbols for each.
The kids were really into this simple activity. I made a Hi-Ya chopping game out of 3 pieces of wood. I used blue painters tape for them to chop. I tried to use brown masking tape but it didn't work as well. That tape cut down the side and didn't leave a noise when chopped. The painters tape chopped down the middle and left a fun vibrating sound when chopped. I used tape because it was the quickest way to reload the chop for the next kid in line. If you build this, make sure the width of the area is wide enough so the kids don't get hurt.
The Brick Wall. This was another great one. Scored 30 of these boxes at a yard sale for $2. At the time I didn't know what i'd use them for but it was too good of a deal to pass up. I used a card stock pattern and traced it with a sharpie to create a brick look. The kids had fun building various towers and then destroying them with their power kicks.
