More my tenth birthday I wanted a big party. To get this I invited 25 girls to go swiming and play games.  My mom loves to plan my parties and is a party genius. We played to old fashioned games first while we waitedd for the late comers ( water baloon toss sack races etc.) Later on once all of the attendees had arrived he had to dive (in teams) for ping-pong balls that my mom had already drilled holes in.  This game was so much fun because the balls had different point values and you didn't know who was going to win by the amount of balls in the there bucket.  We also had a scavenger hunt for things that had been thrown in the pool and the first tea with all of the objects would win. During the whole party there was different food layed out on a table. When it was time for cake we threw six packs of mini soda into the pool and we had to dive for our different sodas to drink ( little did we know that when we opened the sodas they exploded so if you play this game LET THE SODAS SIT). Instead of giving out giftbags to my friends we made flip-flops. To decorate our flip-flops we cut up strips of cloth and you could tie it around the starps, we also used gliter, sequins, googly eyes.  For this craft you coujld use just about anything.  Over all my friends loved my party and we all had a blast.  I had this type of party when i was ten but this is the kinda of party that would work for any age.
