I hope it will be launching WATER balloons, because air-filled balloons have too much air resistance for their mass to be thrown by ANY catapult.
I would recommend bungee cords for the catapult, becayuse they have a very strong spring coefficient and they are very strong and widely available.

A watermelon would be fun to catapult (or a canteloupe, if a watermelon is too heavy.
If you're asking about how to build one, try Googling "catapult."

Go to punkinchuckin.com and look at the picture gallery. These are made to throw pumkins but you get some ideas and scale it down.

go to the lumber yard, or Home Depot and just buy some wood.
