This is a fun game to play outside with water guns!
You’ll just need cups, something to make a hole, string and maybe some tape.
Cut or punch a hole into the bottom of the cup (I made mine close to the edge since the cup is resting on the string) Put the cup on the string through the hole and attach the string to posts or tape to a wall outside.
Use your water guns or other water squirting toy to get the cup to move to the other end. Unless your gun is super powerful you’ll need to pay attention to the direction of the water (good target practice)
You can race your friends to the other side or just practice yourself!
