up balloons for all your party guests.
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.
playing this indoors make sure there is nothing that could get broken or
is great fun to play out in the garden especially if you fill the balloons
with some water.
that no one's clothes are going to get spoilt, or advise to wear outdoor
clothes when inviting guests.
