Blow up balloons for all your party guests.

The idea is that the one left at the end of the balloon fight with their balloon still in one piece and inflated is the winner.

If playing this indoors make sure there is nothing that could get broken or damaged.

This is great fun to play out in the garden especially if you fill the balloons with some water.

Check that no one's clothes are going to get spoilt, or advise to wear outdoor clothes when inviting guests.
