Have you ever surprised your friends with a water balloon fight? I got this idea from my brother. To do this, just fill up enough water balloons for both “teams” (the more you fill, the longer the fight.) Separate the filled balloons into two boxes. Save one for yourself, and deposit the other on your friend’s front porch with a fun sign that explains what’s happening. Then, ring the doorbell and hide. Wait for your friend to answer the doorbell and read your sign before launching the first balloon!
