A great party for summertime; indoor and outdoor activites make this an entertaining choice for children. Make your own invitations my blowing up a balloon and writing on the balloon with a permanent marker. Deflate and send to guests. Clear helium filled balloons floating on the ceiling are a perfect decoration, actually looking like real bubbles. Rent a bubble machine and keep it running in the yard, the kids will go crazy. Purchase jumbo bubble wands (or make your own) and buy (or make your own) bubble fluid, filling a small child size pool and letting the youngsters dip their wands in. Use pool noodles for a game of balloon hockey. Make balloon shaped cookies to munch on! What fun!
