Ahh, it was like Jets verses Sharks ! Water balloons are great for sunny days & a mix of ages ( and boys & girls).

They have 2 techniques

1) the Slam Dunk - just aim & fire the balloons at each other hoping they’ll burst.

2) the Sneaky Spray- holding the balloon by the tie,use a pin ( safety pin-only for older children , prepare to get involved if it’s for younger ones)to make the tiniest hole , the water will then spray out.It’s great for sneaking up on the opposition !

I usually try to prepare quite a lot of balloons otherwise you’ll spend an hour next to the tap doing more & more for wet & giddy kids!
